Keep The Water In Your Pool Cool With These Great Tips
Looking to cool down the water in your swimming pool? Read this article for professional advice on how to keep your pool cool.

As summer temperatures soar, swimming pools, especially those located outside and in direct sunlight, can become uncomfortably warm. While a dip in the pool is supposed to be refreshing, excessively warm water can diminish the experience. Understanding why this happens and how to combat it can help you maintain a pleasant swimming environment for you, your friends, and your family.
Why Does Pool Water Get Warm During the Summer?
The primary culprit behind warm pool water is direct sunlight, which heats the water especially when the pool is exposed to full sun for most of the day. Additionally, high ambient temperatures contribute significantly to the warming of pool water, as the warm air transfers heat to the water both directly and indirectly. Pool systems that circulate water can also distribute heat evenly throughout the pool, preventing cooler pockets from forming. Lastly, a larger surface area exposed to sunlight allows more solar energy to penetrate and warm the water.

Complications from Routinely Warm Pool Water
We all know that very warm water can be uncomfortable and less refreshing. Diving into a pool with bathtub temperature on hot summer’s day can certainly reduce the overall enjoyment of swimming. Additionally, warm water is an ideal environment for bacteria, increasing the risk of infections for swimmers. Algae also thrive in warm, nutrient-rich water, leading to murky water and potentially hazardous swimming conditions. High temperatures can cause pool chemicals to break down more quickly, making it challenging to maintain proper water chemistry and sanitation. This above all is primarily the reason experts suggest pool owners shock their swimming pool during the evening instead of the daytime.
Pro Tip: Shock Your Pool at Night
Pool shock, typically a high dose of chlorine or another oxidizing agent, can easily be broken down by UV rays from the sun, reducing its effectiveness. By shocking your pool at night, you ensure that the chlorine can work effectively without being degraded by UV light. Additionally, cooler nighttime temperatures help maintain the stability of the chemicals, allowing them to work more efficiently and last longer in the water. This ensures a thorough disinfection, killing bacteria, algae, and other contaminants more effectively, and allows the pool to be ready and safe for use the next day without disrupting swimming activities.
Maintain Optimum Balance During Warm Weather
Pool professional, Cole Daasnes of Poseidon Pool Service in Roseville, CA says, “the single most important aspect to maintaining water balance during the hot summer months is having the proper water chemistry.”
Pool Water Testing Guidelines for Hot Weather
Weekly Testing
- Chlorine: Maintain levels between 2.0 to 4.0 ppm.
- pH: Keep within the range of 7.2 to 7.6.
- Cyanuric Acid: Ensure levels are between 30 to 50 ppm.
- Salt Level (for saltwater pools): Maintain between 2700 to 3500 ppm.
Monthly Testing (or as needed)
- Total Alkalinity:
For calcium hypochlorite, saltwater pools, and liquid chlorine pools: 80 to 100 ppm. - Calcium Hardness:
Keep levels between 200 to 400 ppm
For dichlor and trichlor pools: 100 to 120 ppm.
Regions Most Affected
Certain regions of the country are typically more prone to this issue due to consistently high temperatures and strong sunlight during the spring and summer months. These include the Southwestern United States, where states like Arizona, Nevada, and parts of California often experience extremely high summer temperatures. The Southeastern United States, including Florida, Texas, and Louisiana, also struggle with warm pool water due to their hot, humid climates.

How To Cool Your Pool
8 Ways To Cool Down Your Pool Water
Fortunately, there are several strategies you can employ to keep your pool water cool and inviting:
- Pool Covers: Use a reflective or light-colored pool cover to block some of the sun’s rays and reduce water temperature when the pool is not in use.
- Shade Structures: Installing shades, canopies, or pergolas over part of the pool can limit direct sunlight exposure, helping to keep the water cooler.
- Water Features: Adding fountains, waterfalls, or misters can cool the water by increasing evaporation and promoting heat loss.
- Chiller Pump Systems: Investing in a pool chiller or heat pump that can cool the water is a more technical, albeit costlier, solution.
- Nighttime Circulation: Running the pool pump at night when temperatures are cooler can help reduce the water temperature.
- Ice: Adding large amounts of ice to the pool can temporarily reduce the water temperature, although this is not practical for long-term cooling.
- Pool Paint: Using light-colored or reflective pool paint can also reduce heat absorption.
- Drain and Fill: Partially draining the pool and refilling it with cooler water can effectively lower the overall water temperature. However, consider the environmental impact and water conservation measures before opting for this method.
Common Questions About Cooling Your Pool
Do Pool Covers Really Work at Keeping Your Pool Cool?
Using a pool cover can help cool down your pool under certain conditions. If you’re dealing with excessive heat and direct sunlight, covering the pool can block some of the sun’s rays, helping to keep the water cooler. However, if the air temperature is cooler than the pool water, covering the pool might retain heat, so it’s important to consider the ambient temperature.
Additionally, covering the pool can prevent evaporation, which also aids in cooling. If your primary goal is to lower the temperature and the air temperature is higher than the pool temperature, using a cover might be beneficial.
Is Ice The Best Option?
Dumping ice into your pool can provide a quick fix for lowering water temperature, but it comes with potential drawbacks. While it may offer temporary relief from the heat, the cooling effect is often short-lived, especially on hot days or in larger pools. Additionally, adding ice can disrupt the balance of pool chemicals, leading to fluctuations in pH levels and requiring additional adjustments to maintain water quality.
As per a Wall Street Journal report, cooling a 20,000-gallon pool by 10 degrees would necessitate approximately 8,750 pounds of ice, indicating that using ice for cooling your pool off just isn’t a practical approach in the long run. Moreover, using large amounts of ice can be costly and may not be sustainable, considering both financial and environmental implications. While it can be a temporary solution, exploring alternative methods for cooling your pool, such as shade structures or a pool chiller, may provide more consistent and efficient long-term results with fewer potential issues.
Should You Invest in a Pool Chiller?
Las Vegas pool professional, Scott Reynolds, owner of Purpose Pools, sees scorching hot temperatures every single summer. “One piece of equipment we usually recommend to our customers is a pool chiller. They are highly effective in reducing and maintaining a cooler water temperature, often achieving a reduction of 10 to 20 degrees Fahrenheit, depending on the model and pool size. They provide consistent cooling regardless of ambient temperature or sunlight exposure, making them a reliable solution when other methods fall short.”
Today’s modern pool chillers are designed with energy efficiency in mind, using advanced technologies like heat exchange and evaporative cooling to minimize energy consumption while effectively lowering water temperature. Additionally, they are generally durable and require minimal maintenance, offering a long-term solution to managing high pool temperatures. While the initial investment may be higher, the consistent and reliable cooling they provide makes pool chillers a worthwhile consideration for those struggling with excessively warm pool water.
Stay Cool My Friends!
Don’t let the summer heat ruin your poolside fun. Take charge of your swimming experience with these cool strategies. There are myriad ways to beat the heat and keep your pool as inviting as ever. Whether it’s adjusting your maintenance routine, exploring innovative cooling solutions, or simply getting creative with DIY methods, maintaining a cool pool is within your grasp. So, take control of your swimming experience, experiment with different strategies, and ensure that every dip is a refreshing escape from the summer swelter. After all, your pool should be a sanctuary, not a sauna!

Spring Startup Meets Smart Automation With The Attendant
Spring startup meets smart automation with The Attendant, a platform helping improve monitoring, efficiency, water quality, and control.

As spring approaches and the pool season begins to ramp up, automation quickly rises to the top of the list of topics pool professionals discuss with homeowners. Customers want pools that are easier to manage, more efficient to operate, and capable of maintaining consistent performance without constant attention.
For builders and service companies, automation offers a different kind of value. Connected systems can provide better visibility into equipment performance, reduce troubleshooting time, and help identify issues before they turn into costly service calls.
It’s no surprise that the topic continues to dominate conversations heading into every pool season.
Over the past few years, one of the pool automation platforms gaining attention among pool professionals is The Attendant, a connected automation and monitoring system developed by Poolside Tech. The platform combines equipment automation with system monitoring and data visibility, creating a tool designed to help both homeowners and service professionals better understand how their pools are operating.
While many automation systems are designed around specific equipment ecosystems, Attendant was built to integrate with a wide range of pool equipment, giving builders and service companies flexibility when designing or upgrading equipment pads.
But compatibility is only part of the story.
The larger goal behind the platform is to expand the role automation plays in how pools are monitored and maintained.
“Automation used to basically turn things on and off,” explained Ben Forrest of Poolside Tech. “Now we’re talking about systems that think, adapt, and prevent problems before they happen.”

Building an Intelligent Pool System
Traditional automation systems have historically focused on equipment control. Pumps can be scheduled to run at certain times, heaters can be turned on remotely, and lighting systems can be coordinated through a mobile app.
The Attendant builds on that concept by introducing a deeper layer of monitoring and diagnostics.
Through connected sensors and equipment integration, the system collects operational data from the equipment pad and makes that information accessible through a cloud-connected interface. Homeowners and service professionals can observe how pumps, heaters, and other components are operating in real time, providing insight that goes far beyond simple scheduling.
For service professionals, that level of visibility can change how pools are managed. Instead of discovering issues during routine weekly visits, technicians can receive alerts when equipment begins to behave outside its normal operating range.
A pump drawing unusual power, a heater cycling incorrectly, or changes in water conditions can trigger notifications that allow technicians to respond quickly—often before the homeowner even realizes something is wrong.
For homeowners, the system provides peace of mind that their pool is being monitored continuously rather than only during scheduled service visits.
The Attendant Product Line
Poolside Tech has developed several versions of the Attendant platform designed to support different types of installations.
The Attendant
At the center of the lineup is the flagship Attendant controller. Designed for installations where multiple pieces of equipment must operate together, the system functions as a central hub capable of coordinating pumps, heaters, valves, and sensors while collecting operational data about how the system is performing.

Because the platform is cloud-connected, both homeowners and service professionals can access system data remotely through the Attendant interface. Instead of relying solely on periodic inspections at the equipment pad, users can observe system performance in real time.
The goal is to move automation beyond fixed schedules and toward systems that provide a clearer picture of how equipment is operating throughout the day.
The Attendant Mini & The Attendant Mini + Chemistry
For installations that do not require the full scale of the flagship controller, Poolside Tech offers a compact alternative in the Attendant Mini.
The Attendant Mini delivers many of the same monitoring and automation capabilities in a smaller footprint designed for residential equipment pads. Despite its size, the system still integrates with pumps, heaters, and monitoring devices while providing remote access and system alerts through the Attendant platform.

For pool pros, the Attendant Mini offers an accessible entry point for introducing connected automation to residential customers without requiring the larger automation cabinets typically associated with advanced systems.
The platform expands further with the Attendant Mini + Chemistry configuration.
This version incorporates probe-based sensors that continuously monitor water balance parameters such as pH and sanitizer levels. Instead of relying exclusively on manual testing during service visits, the system provides ongoing readings that allow service professionals to observe trends in water chemistry over time.
“If a builder offered homeowners a system that keeps chlorine and pH perfect no matter how many kids are in the pool,” Forrest said, “almost everyone would say yes—as long as it’s affordable.”
By integrating water monitoring with equipment automation, the Attendant platform aims to help service professionals maintain more consistent water conditions while reducing the guesswork that often accompanies traditional testing routines.
Building Momentum Across the Industry
While the Attendant platform has steadily evolved over the past several years, Poolside Tech has also been working to introduce the technology directly to the professionals who build and service pools every day.
In recent seasons, the company has made a strong presence at industry trade shows, conferences, and educational events, demonstrating the platform to builders, service companies, and distributors across the country.
Those efforts have helped Poolside Tech build a growing network of partnerships across the pool industry, beginning with major manufacturers like Latham and extending to distribution relationships with organizations such as POOLCORP and Heritage Pool Supply.
The company has also developed connections with several prominent industry buying groups, including Carecraft, United Aqua Group (UAG), and Master Pools Guild (MPG). These organizations help introduce new technologies to members who are continually looking for tools that can improve operational efficiency and customer experience.

Pool Pros Embracing Connected Automation
Service companies have also begun exploring how connected monitoring platforms can improve day-to-day operations. Organizations such as Poolwerx are working with Poolside Tech in their efforts to streamline service routes, reduce troubleshooting time, and provide greater visibility into pool performance between service visits.
Companies such as Shasta Pools are also exploring how connected monitoring platforms can support both sides of their operation. As a company that builds pools while also maintaining a large service and repair division, Shasta is working with Poolside Tech to adopt automation and monitoring technology that gives homeowners greater visibility into how their pool systems are performing while helping technicians keep a closer eye on equipment between service visits. For Shasta, integrating connected automation is part of a broader effort to improve the long-term ownership experience as smart home technology continues to expand into the backyard.
A Changing Landscape for Pool Automation
Automation has come a long way from the simple timers that once controlled pumps and heaters.
Today’s connected systems provide real-time insight into equipment performance, allowing homeowners and service professionals to monitor pools more effectively than ever before.
Platforms like Attendant represent an evolution in how automation is being designed—combining equipment control, monitoring, and operational data into a single connected environment.
As the new pool season approaches and automation once again becomes a central topic of conversation, it’s clear that the technology is continuing to evolve.
That’s why this spring, the goal is no longer just convenience. It’s making pools easier to manage, more efficient to operate, and better understood by the people responsible for keeping them running.

Pool Maintenance
The Hidden Liability of a Green Pool

When a green pool is simply left to turn into a stagnant, algae-infested basin, it isn’t just an eyesore—it can become a serious public-health and legal hazard. Neglected pools serve as ideal breeding grounds for mosquitoes capable of transmitting diseases such as West Nile virus and Zika virus.
From a pool-industry perspective, the issue is clear: an unmaintained pool is not simply a dormant asset—it can generate liability, drive down property values, invite municipal code enforcement, and create safety hazards beyond the usual concerns of drowning, slip-and-fall, or equipment failure.
Neighbor’s Viral Photo Raises Questions About Pool Neglect and Liability
After a photo of a backyard pool completely overtaken by algae and vegetation began circulating on Reddit, it quickly became a viral talking point. The photo wasn’t taken by a passerby or an inspector—it was snapped by a frustrated neighbor fed up with living next to what had become a swamp. The homeowner had apparently abandoned their pool a decade ago, leaving it to fill with algae, debris, and rainwater until nature completely reclaimed it.

When the neighbor shared the image online, the post went viral, and commenters couldn’t believe it was once a swimming pool. Many asked how anyone could be allowed to let their pool reach that point and why local authorities hadn’t stepped in. Beyond the shock factor, the discussion struck a nerve—it wasn’t just about aesthetics, but about responsibility, public health, and the fine line between private property rights and community wellbeing.
Homeowner Responsibilities When a Pool Is Neglected
In many jurisdictions, local codes define standing water that can breed mosquitoes as a “public nuisance.” For example, the City of Los Angeles Municipal Code states that any standing water on private property that has become a breeding source for mosquitoes is declared a public nuisance and an immediate threat to public health.
Similarly, under California law, county health-agency information sheets note that neglected swimming pools may produce millions of potentially infected mosquitoes and that local vector-control agencies may enact abatement proceedings, impose fines of up to $1,000 per day, or place a lien on the property.
In short, a homeowner who allows a pool to remain stagnant and untreated may find themselves subject to enforcement action, abatement costs, and fines or judgments.
Code Enforcement & Abatement Processes
In the City of Huntington Park, California, ordinances require property owners to maintain swimming pools in a manner that does not allow mosquito breeding, including emptying or keeping dry any pool that is abandoned or not in service. Violations are considered infractions punishable by fines.
In Los Angeles, vector-control authorities can issue a 72-hour notice to secure and abate the nuisance; failure to comply can result in misdemeanor charges. The municipality may then perform the abatement work and bill the cost to the property owner, often adding administrative surcharges.
For pool builders, remodelers, and service contractors, this highlights a key education point: failing to act is not just the homeowner’s problem—it can quickly become a legal one.
General Liability: Premises & Attractive Nuisance
Beyond mosquito-vector issues, neglected pools still carry the classic “attractive nuisance” liability. Legal experts note that when a property includes a feature likely to attract children—such as a pool—a homeowner owes an increased duty of care, and failure to maintain it may heighten civil liability.
Combine that with visible neglect (green water, unsecured fencing, vegetation overgrowth), and a homeowner may face multiple forms of exposure: vector control, code violation, and premises liability.
Public Health & Neighborhood Impacts
From a public-health standpoint, a single neglected pool can become a prolific mosquito nursery. Health agencies report that mosquito eggs can hatch in as little as 7 to 10 days in stagnant water, and that one neglected pool can produce millions of mosquitoes in a single summer.
Neighborhoods and HOAs should take note: one person’s abandoned pool quickly becomes everyone’s problem. Municipalities are increasingly monitoring such sites, especially in areas prone to vector-borne disease.
Practical Alternatives: What Should Homeowners Do Instead?
Evaluate: Remove, Mothball or Maintain?
When a homeowner asks what to do instead of watching their green pool turn into a mosquito resort, the answer depends on intent and condition. Three main strategies emerge.
1. Full Removal or Back-fill
If the pool is no longer in use and there’s no plan to service it, complete removal or back-fill may be the most responsible course. The Pool & Hot Tub Alliance recommends draining, filling, and rendering an abandoned pool incapable of holding standing water.
From a liability standpoint, this eliminates the basin, the standing-water hazard, and ongoing obligations.
2. Mothballing (Seasonal Maintenance and Covering)
If the pool might be used again, seasonal maintenance and proper covering is the practical alternative. This means keeping water circulating and sanitized, using a secure ASTM-rated safety cover, removing debris, and ensuring no place for stagnant water to accumulate.
Simply covering a pool with a loose tarp isn’t enough; water can still collect on the surface, providing mosquito habitat and a drowning hazard.
3. Active Maintenance (In-Use Strategy)
If the pool remains in use, standard maintenance applies: circulation, filtration, sanitation, and algae control. Even when not used daily, the system cannot simply be turned off. Well-maintained pools eliminate food sources for mosquito larvae and reduce the chance of infestations.
Annual inspections or off-season maintenance remain good practice for responsible homeowners.
Role of Pool Builders and Service Companies
This topic creates a strong value-add opportunity for pool professionals. Educate homeowners about the risks of abandonment, offer winterization or closure plans, and provide turnkey removal options. Present written proposals outlining costs, compliance issues, and long-term benefits. Helping clients make informed decisions reduces liability for both homeowner and contractor.
Neighborhood and Public-Health Impact
| Condition of Pool | Mosquito Breeding Risk | Potential Legal/Code Consequence |
|---|---|---|
| The pool is fully maintained and in use | Minimal – filtration and sanitizer remove larvae | Standard homeowner liability (fencing, drowning) |
| Pool inactive but drained/back-filled | Low – no standing water | Low code-risk if properly closed |
| The pool is inactive but covered, yet water remains | Medium-high – water on the cover or basin supports breeding | Moderate code risk unless cover meets safety specs |
| Pool inactive, no maintenance, green water | High – millions of larvae possible | High risk of abatement, fines, lien, or criminal sanction |
| Pool inactive, unsecured, green water | Very high – drowning + vector hazard | Highest risk: multi-agency enforcement |
Key Takeaways
• Neglecting a green pool can lead to fines, liens, or criminal penalties.
• Every homeowner must decide responsibly: maintain, mothball, or remove.
• Doing nothing is the riskiest and costliest choice.
• For professionals, this is an educational moment to reinforce that pools require stewardship—not abandonment.
Final Thoughts
When a homeowner says, “I’m just going to stop using it and let nature take its course,” what they are really doing is inviting legal and environmental trouble. For the pool industry, this is an opportunity to emphasize that our role extends beyond construction and service—we also help protect communities from public-health hazards.
A neglected pool isn’t just unsightly; it’s a potential liability and a vector-control issue. By guiding homeowners toward maintenance, proper closure, or removal, we help preserve not only their property but also the well-being of their neighbors.

Acid Washing Safety: What Every Pool Pro Should Know

There’s something deeply satisfying about seeing a dull, stained pool surface turn bright and clean again after a good acid wash. It’s like hitting the reset button on a pool that’s seen better days. But as any seasoned pool pro knows, this powerful process comes with some serious risks.
Acid washing uses muriatic acid (hydrochloric acid)—a chemical strong enough to dissolve mineral buildup, algae, and stains. That same strength, though, can cause burns, lung damage, and serious injuries if not handled the right way. Knowing how to stay safe isn’t just a good idea—it’s essential for protecting yourself, your crew, and your customers.
Why You Can’t Cut Corners on Safety
Muriatic acid is no joke. A splash on your skin or a breath of concentrated fumes can do real harm in seconds. It can also eat away at pool finishes and metal fixtures if it’s not used properly. The goal is to make the pool look better—not cause damage or danger along the way.
When you follow safety protocols, you’re not just checking boxes—you’re building a reputation for professionalism and responsibility that customers notice.
Safety Basics Every Pool Pro Should Practice
1. Paperwork Isn’t Just Paperwork
Before you start mixing anything, make sure your Hazard Communication Program is up to date. Have Safety Data Sheets (SDS) for every chemical you use, and double-check that all containers are clearly labeled. This may seem tedious, but if something goes wrong, this documentation can be a lifesaver—literally and legally.

2. Dress Like You Mean It
When you’re handling acid, jeans and sunglasses aren’t enough. You’ll need:
● Acid-resistant gloves (rubber or neoprene)
● Chemical splash goggles and a face shield
● Long-sleeved acid-resistant clothing or a Tyvek suit
● Closed-toe, chemical-resistant boots
● A respirator with acid-gas cartridges if ventilation isn’t great
It might not be a fashion statement, but it’s definitely a safety statement.

3. Let It Breathe
If you’re working in an indoor pool or a deep end, acid fumes can build up fast. Always use fans, open doors and windows, and wear a respirator if needed. OSHA even considers an acid-washing pool a permit-required confined space—so don’t take chances. When in doubt, step out and get fresh air.

4. Mix with Care
There’s one golden rule every pool pro should memorize: Always add acid to water—never water to acid. Doing it backwards can cause an instant, violent reaction that splashes acid everywhere. Mix outdoors, use plastic containers, and keep people (and pets) far away while you work.

5. Be Kind to the Environment
Once you’ve finished the wash, it’s time to neutralize the leftover acid with sodium bicarbonate (baking soda). Never let untreated acid flow into a storm drain or onto the lawn. Not only is that harmful, it can also get you in trouble with local environmental agencies. Take a few extra minutes to neutralize properly and practice disposal according to local rules.

Two Is Better Than One
Whenever possible, don’t go it alone. Have another technician on deck while you’re in the pool. That second person can pass tools, monitor fumes, or call for help if something unexpected happens. It’s simple teamwork that makes the job safer for everyone.

Be Ready for the “What-Ifs”
Even with the best precautions, accidents can happen. Make sure you have:
● An eye wash station or portable eyewash bottle within arm’s reach
● A fresh water source nearby for rinsing skin or eyes
● A neutralizing agent like baking soda ready to go
● Up-to-date first-aid training for handling chemical exposure
At Pool Troopers in Tampa, FL, for example, every employee is issued proper safety gear and trained on SDS procedures—an approach all pool companies can learn from.

The Bottom Line
Acid washing is one of the most dramatic makeovers you can give a pool—but it’s not something to take lightly. The right preparation, gear, and mindset make all the difference between a successful job and a dangerous one.
If you’re looking to sharpen your safety skills, check out the OSHA 10 Course for Pool Pros that I offer through Space Coast Pool School. It’s a great way to stay informed, stay compliant, and most importantly—stay safe.
