Pool pH regulators

To raise the pH of a swimming pool, you need to use a product called "pH Plus," usually composed of sodium carbonate or sodium bicarbonate. It's added to the water to reduce acidity and stabilize the pH. Ideally, you should measure the pH before adding the product, then follow the manufacturer's recommendations based on the volume of your pool. Good water circulation also helps distribute the product evenly and achieve a stable reading after a few minutes. The goal is to bring the water's pH back into the ideal range, around 7.4 to 7.6.

To lower a pH that is too high, a product called "pH Minus" is used. This product brings the water back to a more stable and comfortable level for swimmers. Before adding pH Minus, you need to know the volume of your pool and the current pH level. Pour the product slowly into the water, with the filtration system running, and wait several minutes before testing again to ensure the pH has returned to the recommended range. The goal is to stabilize your pool's pH within the ideal range, around 7.4 to 7.6.

A pH that is too low can be caused by acid rain, the excessive addition of acidic products (such as some shock treatments), or heavy pool use. A low pH makes the water more corrosive, which can damage surfaces and equipment, and irritate the eyes and skin. It is therefore important to adjust the pH quickly with a pH Plus product.

The pH can naturally rise when the water is harder (rich in minerals), or when the water is highly agitated (waterfalls, spas, jets). Some treatment products also contain alkaline elements that raise the pH. A pH that is too high reduces the effectiveness of chlorine, promotes limescale buildup, and can make the water cloudy.

Most test kits typically call for 5 drops of pH reagent in the water sample. However, the exact number can vary depending on the brand of tester. Therefore, it's important to read the instructions provided to obtain an accurate measurement. Using the wrong amount of reagent can skew the result.

The amount needed depends on the water volume and the current pH level. Manufacturers provide a dosage chart indicating how many grams or milliliters to add to correct a pH that is too high. It is advisable to add the product in small doses, wait a few minutes, and retest to avoid lowering the pH too much.

Just like with pH Minus, the exact dosage varies depending on the pH level and the size of the pool. pH Plus products come with a dosage chart indicating how much to add to raise the pH to an optimal level. It is best to add the product gradually for precise adjustment.

After adding pH Plus, the product typically takes effect within 30 minutes to 1 hour. Water circulation helps to distribute and dissolve the product. It is important to retest after this time to check if the value has stabilized and if further adjustment is needed.

Adjusting the pH with pH Minus usually takes a few minutes, often between 30 minutes and 1 hour depending on water circulation and the amount of product added. Once this time has elapsed, a test should be performed to confirm that the pH has returned to the ideal range.

The ideal pH level for a swimming pool is between 7.2 and 7.6. This range ensures good comfort for swimmers, optimal chlorine effectiveness, and protection of equipment. A pH that is too low or too high can cause irritation, corrosion, limescale buildup, or cloudy water.

To add pH Plus or pH Minus, first measure the current pH level, then consult the product chart. Next, dilute the recommended amount in a bucket of warm water, then pour the mixture around the pool, keeping the filtration system running. This allows the product to disperse evenly and work more quickly.

Adjusting the pH begins with testing to determine the current value. If the pH is too low, add pH Plus; if it's too high, add pH Minus. Always proceed in small amounts, let it sit for several minutes, then repeat the test to verify the effect. A gradual adjustment provides a more precise result and avoids sudden fluctuations.
