Cyanuric acid is a common name in the pool business. It constitutes the tool compartments of private and business pool service experts who maintain outdoor pools. Since its creation in 1829, CYA has been useful in keeping chlorinated pools safe and clean. On the other hand, researchers and legislators have brought up the issue of excess use of CYA. They claim it can prompt serious public health outbreaks and pool maintenance problems. Further complicating the issue, some inspectors demand the use of cyanuric acid, while others forbid its use. This article aims to enlighten on the reasons behind the divided responses.
Cyanuric is a different acid from muriatic acid. The pool business uses it to control and adjust pool pH levels. When buying, it exists either as an independent item or as a beneficial addition to the chlorine dosage. It dissolves in water having minimal impact on pH, hardness or alkalinity. It varies from other acids as it stabilizes the chlorine in the water. Cyanuric acid forms an impermanent bond with chlorine. It combines with the free chlorine in the water hence weakening it. The most important thing is that it shields chlorine from the sun. It will do this until it fulfills its purpose of oxidation to disinfect the pool.
Existence of chlorine in the pool will still remain in the presence of CYA, even during the day. Lack of a stabilizer will cause chlorine to disappear, hence leaving the pool unprotected after a short period. It is worthwhile to note that cyanuric acid will remain unused and builds up with time.
Cyanuric acid has a number of advantages for the pool business. It has permitted the regular homeowner, HOA and pool experts to manage the pool’s water chemistry with ease. Managing the pool water weekly rather than daily has made it easier for service providers to deal with more pools with fewer worries. This has also reduced the number of emergency calls caused by algae growth in pools.
In general, the market for cyanuric acid has grown, with profits of around $300-million per year. The confusion that adding extra than the required amounts increases the benefits has propagated through the pool business. This misconception does not apply in the pool industry, and you shouldn’t adopt it. How about we research the scientific reasons behind the failure of the stated misconception and why the significance of cyanuric acid measurements is key in maintaining clean and safe pools.
Results of high CYA levels
Chlorine’s capability to oxidize, potentially measured as oxidation reduction potential (ORP), is a reliable marker of chlorine’s viability.
Throughout the years, various researches have shown that when cyanuric levels rise in the pool, ORP levels drop. This shows that the effectiveness of chlorine reduces. What’s more, there is a relationship between high levels of cyanuric acid and the period taken to eliminate present pathogens in pool water successfully.
Besides, increased levels of cyanuric acid, renders chlorine ineffective in destroying the most hazardous microorganisms in water such as cryptosporidium parvum.
Cryptosporidium parvum, or crypto, is a microorganism resistant to chlorine. This causes gastrointestinal ailment, like that of Giardia, which reproduces in the human gut.
Crypto has a solid and sturdy external shell, an adaptation to survive outside the human body. It spreads through pool water or drinking water. It can adapt to different levels of chlorine concentration.
Each year, large numbers of cases concerning cryptosporidiosis in public pools, emanate from fecal waste. At the point when a matter associated with crypto happens, the Centers for Disease Control and Prevention suggests a free chlorine concentration of 20 ppm for 32 hours to destroy 99.9% of cryptosporidiosis in the pool (CT=15,300 mg*min/L).
Nonetheless, the CDC proposal doesn’t take into consideration the degree of cyanuric acid present in pools.
The latest CDC research brought forth at the 2015 World Aquatic Health Conference, shows that CYA levels that are low as 10-20 ppm in a highly chlorinated pool aren’t sufficient to destroy the required 99.9% of crypto in pool water. It likewise states that additional techniques and other sanitization frameworks to shield swimmers from health-related conditions caused by the fecal matter are necessary.
Thorough education and training on the advantages and abuse of cyanuric acid are important. Poolside kits precisely meant to test for CYA are accessible in the markets just that they are rarely used if not used at all.
When the level of cyanuric acid is high, the primary dependable technique for expelling CYA from pools is through depleting/weakening or elimination using the process of reverse osmosis.
Pool Metals and Metal Staining
Metals are naturally existing elements found in every place; in water, soil and stones. Metals in soil and stones dissolve in acidic rainwater, which is then carried to surface water and groundwater. Through this, the dissolved metals find their way to pools and tubs when filled. Exposure of metals to water cause staining on pool surfaces and equipment. This article discusses the techniques to control the presence of pool metals. It also discusses the different kinds of metal staining and the relevant chemicals to eliminate and hinder stains.
Metals in pools and hot tub water
There are 91 existing metals, but only 6 are problematic to hot tubs and pools. The 6 metals include magnesium, copper, cobalt, iron, manganese and calcium. Here we will only discuss 4 that are cobalt, copper, magnesium and iron.
Fill water, inclusive of almost all municipal and well water supplies that fill hot tubs and pools, contains a few metals. It is advisable to test for metal concentration in source water before filling the hot tubs and pools.
Tests for iron and copper are easily accessible, though the majority only measures the free form of the dissolved metals. They also do not test the sequestered and complexed forms of dissolved metals. A two-phase metal test containing adequate reducing and releasing agents give better results on free, complexed and some oxidized metals.
Sources of metal contamination in the pool and hot tub water are plaster and pebble surfaces, water features, decking materials, metal equipment, galvanic corrosion, chemicals and runoff.
In addition, flagstone, marble and stone contain iron that leaches into the pool after every rainfall. Imbalanced water may cause the introduction of copper from heat exchangers found in gas-fired water heaters. Moreover, copper-based algaecides and mineral-based water treatment may be a source of pool metals. Plant fertilizers can also introduce metals when incorrectly applied or due to uncontrolled flooding. More sources of metal include irrigation methods with well water.
Avoid using untreated water with high metal concentration (higher than 1ppm) in hot tubs or pool. Treat the water when the metal concentration is higher than 0.2 ppm. Sediment filters (10 microns or less) eliminate the majority of the bigger oxidized particles. Use filters that have metal adsorbents to treat water, to minimize dissolved metals concentration.
Primary Sanitizers and Stabilizers
Maintain proper concentration of primary sanitizers and other similar stabilizers to prevent organic contaminants. These include; pathogens, non-hazardous bacteria and algae minimizing the need for a copper-based algaecide.
Bonding of Metals and Water
The majority of the pool and hot tub equipment are metal-made. For example, electrolytic halogen generators, the heating core of electric heat pump, gas-fired pool and hot tub heaters, ladders, light rings and handrails.
To enhance chemical and electrical safety, install a bonding system in the hot tub or pool. The bonding system involves joining the copper wire with all the metal elements and water combined. This minimizes electric potential difference. Lack of this system, enables dissolution of pool metals, causing staining that damages the equipment. This is the process known as galvanic corrosion and can heighten due to several factors such as salt water, stray direct current as well as its power supplies. Anodes (zinc metal) reduce the damage on the equipment but don’t deal with the cause of corrosion. Test the bonding system every year, or any other time there is corrosion.
Pool & Hot Tub pH
pH is the most vital yet most ignored factor in preventing metal release in water. Low pH water (below 7) is acidic and corrosive. Acidic water dissolves metals from the pool equipment.
Improper water chemistry harms pool surfaces and machinery. Always ensure to maintain an accurate pH, alkalinity (carbonate) and calcium (hardness). If inadequate, water draws carbonate and calcium from cementitious surfaces, discharging metals into the water.
Sequestering agents join with the dissolved pool metals to reduce oxidation hence reduces staining. They chelate the metals, not eliminate them. They require a complex modern ultra filtration system to remove sequestered metal particles as the particles are too small for the pool filtration system. Add this agent on a regular basis, as a secondary disinfection and primary sanitizer systems keep on destroying them.
Ways to reduce metal concentration in hot tubs and pool water
- Bind the metals using polymer and water-insoluble natural adsorbents
- Filter the water through a reverse osmosis system
- Remove and replace a part of the water with fresh metal-free water
Removing stains from the pool and hot tub surfaces
1. Metal stain removal from the surface
2. Chelation of the dissolved metals in the water with a sequestering agent
3. Elimination of the metals from the water.
To get rid of pool metals and metal stains, add oxalic acid, ascorbic acid and citric acid or a similar product into the pool water. An experienced pool service expert should only execute the use of Muriatic acid in the removal of metal stains as it can lead to permanent damage to the pool surface. Chelation of dissolved metals and minimizing concentrations of dissolved metal have been earlier tackled.
Figuring out the difference between metal stains and those by organic contamination can be difficult. For evaluation, establish the origin of the stain, asses the water chemistry and test the stain with either citric acid or ascorbic acid.
Note: Some organic stains, similar to those brought about by iron bacteria, vanish after treatment with ascorbic acid but return with the introduction of chlorine residuals.
Selling Automatic Pool Cleaners Online
Amidst the pandemic this summer, Rene Huston, president of Patio Pleasures acknowledges an increase in their sales, of up to 10 pools in a day, if available. The unanticipated pandemic that led to the cancellation of travel plans had people invest that money for their backyard luxury. This is no wonder; there is an increase in the sales of automatic pool cleaners, especially high-quality robotic models. Clients also opt to invest cash they would have used elsewhere to enjoy the benefits of the long-term, cost-efficient APC’s.
Since their introduction in the 1950s, automatic pool cleaners have become part of pools in North America due to their personality and efficiency. They move around the pool on their own, cleaning the pools, hence minimizing the need for manual vacuuming and sweeping.
Jeannie Pearcy, owner of SwimFun Pool & Patio in Olathe, Kansas, United States, tells her clients a pool cleaner is similar to a Roomba for your pool.
Recently, online competition affected APC sales at brick and mortar vendors. Reacting to retailer’s complaints, APC producers began making ‘trade-only’ products. These products are only physically accessible through pool and spa shops. These products come with extra features like additional supplies longer warranties or refundable offers. Furthermore, you can access and depend on service from the vendor and manufacturer. Discussing with pool and spa vendors, there are varying opinions on the sell of automatic pool cleaners.
Store manager for Outback Pools & Spas in Wichita Falls, TX., Jimmy Cooper, appreciates manufacturers for looking out for their welfare too. Clients get to experience what a brick and mortar can do. Customers can purchase these pool products online though you can have horrible encounters with them. This gives the stores a chance to enlighten clients on what they can do.
Online vs Retail stores
It may seem like the ideal service to request for a robotic automatic pool cleaner from your home and have it brought within two days. However, their satisfaction can be short-lived either with the delivery of the wrong product or early failure of the product.
Most clients come to Huston’s store, complaining of an ineffective online product. They use this opportunity to explain the advantages if they had bought it from them. Such discussions and encounters build the confidence of customers in brick and mortar vendors.
Moreover, when online clients take their automatic pool cleaners to Cooper’s store for maintenance or service, he cannot do anything about it because the product is not from his store. He instead offers to sell them a similar product from his store. To ease their frustrations, he explains the benefits of buying from stores.
With this approach, Cooper believes he has changed the opinion of half of the online buyers to in store clients.
For years, Huston has avoided servicing online bought goods. However, now her opinion has begun to change. At times, it depends on how busy they are at a particular time though she’s still unsettled. She’s a bit receptive, taking into consideration the profits they could earn.
One of the significant selling points of an automatic pool cleaner is its ability to somehow get rid of the pool guy, as Cooper states.
Cooper calculates with his clients an hour service each week for a year in comparison to purchasing a cleaner. They realise a $1000 or $1500 cleaners operating two or three hours in a day for a year is cheaper than they thought.
The service crew is not always there, and the pool requires cleaning between their visits. Even with an automatic pool cleaner, manual work like scrubbing the pool walls requires the service crew. Depending on the water environment, manual vacuuming may also be necessary.
Selling Game Plan
Since APCs are more virtually intriguing compared to other pool equipment, retailers depend on popular displays in the store to start a discussion with a client.
After capturing the customer’s attention, Huston urges would-be buyers to go with a unit home and try it out. This program at Patio pleasures permits clients day access to the unit. When returned, they do a far check to ensure the unit is clean, the baskets and other pieces still in place.
The program, try before you buy, has also worked for Pearcy. Even if the Client does not purchase the unit, then, they include it in their purchase wish list and save up for it. Furthermore, SwimFun sells the season’s trial unit at a cheaper price with a limited warranty.
Cooper recognizes that persuading clients on the advantages of an automatic cleaner has become simpler. This is due to the increase of dependence and convenience of technology though some purchasers are still ignorant.
With a number of sales strategies in place, verbal means is the most powerful convincing method in the sell of automatic pool cleaners. This is the reason the product will remain a powerful sale in the retail sector.
Huston notes that pool owners are seeking ways to maintain their pools happy and healthy. Time is of the essence; get an automatic pool cleaner as it is the ideal choice for your pool.
