7 Important Pool Maintenance Tips to Keeping a Clean & Healthy Pool
Regular maintenance and cleaning are necessary to keep your backyard pool in top condition for fun and relaxation during the hot summer months. To help you achieve this goal, here is a step-by-step guide on how to clean your residential pool:
Step 1: Skim Your Swimming Pool
To maintain a clean and hygienic pool, it’s crucial to remove any debris floating on the water’s surface using a pool skimmer net. Here are the main pool maintenance tips to remember:
- Skimming the pool surface regularly prevents debris from sinking to the bottom and making the pool more difficult to clean.
- Use a pool skimmer net to remove leaves, insects, or any other debris from the water surface.
- Check the skimmer basket and empty it regularly to maintain good water circulation and avoid clogging.
- Skim the pool surface before using any other cleaning equipment to avoid stirring up debris that has settled on the pool bottom.
- Make sure to skim the pool surface at least once a day during peak use or when there are high winds and storms.

Skimming your pool surface before cleaning is an essential first step in pool maintenance. This initial process helps to remove leaves, insects, and other debris from the water’s surface, preventing clogs in your pool cleaning equipment. Furthermore, debris left in the pool can lead to the growth of bacteria and other harmful organisms, posing a health risk to swimmers. Additionally, a pool with debris floating on the surface looks uninviting, and regular skimming can help to maintain the pool’s appearance.

Step 2: Brush Your Pool Interior
To remove any algae or dirt buildup from the pool walls and floor, use a pool brush to scrub the surfaces thoroughly. Areas that are shaded or not well-circulated need extra attention as they are more prone to algae growth. Consider the following pool maintenance tips when choosing the right brush for your pool:
- The type of brush you need will depend on the surface of your pool.
- If your pool surface is unpainted concrete, use a brush with both stainless steel and nylon bristles.
- For gunite pools, a brush with stainless steel bristles is recommended.
- For fiberglass, vinyl, or painted concrete surfaces, use a brush with nylon bristles only.

Selecting the right brush for your pool surface is critical to effectively remove debris, algae, and other buildup, ensuring a clean and clear pool.
When brushing your pool, here are three things to keep in mind:
- Pay extra attention to shaded or poorly circulated areas, as these areas are more likely to develop algae growth and require more frequent brushing.
- Choose the appropriate brush for your pool surface material to avoid damage and ensure effective cleaning.
- Use overlapping strokes and apply enough pressure to remove any buildup or debris from the walls and floor of the pool.

The Rise of pH
Is your swimming pool pH rising and you don’t know why? Learn how to prevent the rise of pH in your pool with these two proven methods.

Understanding pH
pH is a symbol for the power of hydrogen. Any chemical that contains hydrogen is considered an acid. There are weak acids and strong acids. Muriatic acid is also known as hydrochloric acid. Muriatic acid is made by taking hydrogen chloride and dissolving in water. This produces hydrochloric acid which is known as a strong acid because it has a high percentage of hydrogen. The term “muriatic” means “pertaining to brine or salt” since it originates from the production of pure chlorine combined with hydrogen. When hydrogen chloride is dissolved in water you have hydrochloric acid. The main takeaway here is the presence of hydrogen. A high percentage of hydrogen ions in pool water will lead to a lower pH.
There are base or alkaline chemicals such as soda ash (sodium carbonate) or baking soda (sodium bicarbonate). These are salts that contain a higher percentage of hydroxyl ions over hydrogen and therefore will raise the pH. The formation of hydroxyl ions from the addition of soda ash leads to the consumption of hydrogen which drives the pH up.
The Unintended Side Effect of Modern Pools
Pools now are designed with waterfalls, fountains, negative edge, and raised hot tubs. The latest system designs include SWG saltwater generators, ozone, and AOP Advanced Oxidation Process. All of these new items offer a plethora of benefits from better-sanitized water to the peaceful ambiance of a backyard water oasis.
These new trends all have one thing in common. They create either aeration or turbulence of the water that leads to the increase of pH. Swimming pool water contains a collection of chemical species. Water balance species include carbonate ions (CO3-2), bicarbonate ions (HCO3–), carbonic acid (H2CO3) and carbon dioxide (CO2). Normally, all of these exist in equilibrium.
Aeration and Turbulence Raise the pH
All of the devices named will cause the pH to rise. Here’s how; When air is forced into water it breaks the equilibrium of CO2 between the air and water. This is a violation of Henry’s Law which states that the amount of gas in a liquid is in proportion to that of the same gas at the surface. The first phase here is that aeration causes the water to off-gas CO2. This upsets the equilibrium of all the species and causes the consumption of hydrogen. When hydrogen is consumed the pH goes up. Aeration and turbulence are present in ozonators from the bubbling of the O3 gas. In saltwater generators, chlorine gas is produced at the positive cell and sodium hydroxide and hydrogen gas are made at the negative cell. The bubbling from these gases is enough to cause turbulence and increase pH. Obviously, when waterfalls or fountains run continuously there is high aeration which leads to increased pH. Raised hot tubs that spill over into the pool will increase pH due to the aeration from the jets and the turbulence of the overflow from the hot tub to the pool. High negative edge drops also create turbulence that increases pH.
Two Ways to Ease The Rise in pH
The ideal standards for pH are between 7.4 to 7.6. High pH can lead to:
- Lowered percentage of active killing agent from chlorine (with or without CYA)
- Scale formation
- Metals will stain at pH of 8 or above especially copper
- Cloudy water
- Reduced Oxidation Potential Reduction ORP
There are two very simple ways to reduce pH increase.
One: Keep the total alkalinity at a target between 70-80 ppm. High total alkalinity can be lowered by 10 ppm using 25.6 fl.oz. of muriatic acid in 10,000 gallons of water. Be sure to test and account for the cyanuric acid CYA that contributes to total alkalinity. If there is CYA present in the pool over 50 ppm 1/3 of the CYA reading must be subtracted from the total alkalinity test to get the correct carbonate alkalinity. With the total alkalinity lowered by acid to between 70-80 ppm the pH may decrease below 7.0. You can aerate by using the running waterfalls etc. in the system to raise the pH to 7.4-7.5 without having any effect on the total alkalinity. The pH can be managed better at these levels and less acid will be needed to keep pH down. The LSI can be helpful here as well. Where total alkalinity is kept is also based on the primary sanitizer used. Trichlor is an acidic form of chlorine so it will lower both pH and total alkalinity. In this case the alkalinity can be maintained at 80-90 ppm. If using cal-hypo or liquid chlorine 60-70 ppm is preferred.
Two: Add borates to slow down the rise of pH. Adding borates at a level of 50 ppm will help considerably to slow the rise of the pH in pools with water features or devices that produce turbulence. Adding borates can help conserve the amount of muriatic acid needed to control a rising pH.
Everything related to water is about balance. Proper management of total alkalinity and the addition of borates can help to restore balance and slow down the rise of pH in pools with high aeration.
