Leslies Ph Down (2024)

FAQs

Does pH down actually work? ›

pH Down is most effective when used in water with a neutral pH, as the higher the pH, the more carbonate hardness that water will have, and something called buffering occurs. High carbonate hardness maintains a high pH, or pH can drop and then rise again, due to buffering.

After adding pH increaser or decreaser you'll want to wait about two to four hours, although some chemical manufacturers suggest a full turnover cycle, before retesting. The smaller the increments you need to adjust for pH, the less time you'll need to wait for the results to become stable.

Any activities that reduce your stress load, decrease your exposure to toxins and/or get you to breathe deeper will reduce acidity in the body. Exercise. Moving and sweating helps remove acidic waste from the body as well as improve your breathing patterns.

If the pH gets higher than 7.8, the water is becoming too alkaline. When water is too alkaline, it reduces the effectiveness of chlorine — the pool chemical that kills pathogens. Water with a pH that's too high also can cause skin rashes, cloudy water and scaling on pool equipment.

1. Muriatic Acid (HCl) Muriatic acid, the most commonly used pH reducer, is a relatively expensive liquid acid that has a pH of less than 2 at the 31.45 percent concentration that is typically used in pools.

Since rain is naturally acidic with a pH of up to 5.5, when a substantial quantity of rain dissolves in pool water, it decreases its pH levels. Other than natural elements, frequently using the pool might also drop the pH levels, as can improper water chemicals, especially the DIY kind.

Measure 1 US tbsp (15 mL) of plain white vinegar and pour it into 1 US gal (3,800 mL) of water. The natural acidity of the vinegar will help neutralize the alkalinity in the water, bringing a pH of 7.5-7.7 down to about 5.8-6.0. Vinegar has a pH of 2-3 and lemon juice has a pH of 2, so their effect on water is similar.

8) How long after adding chemicals can I swim? Alkalinity Balance, pH up, pH down, Calcium Balance, Water Stabilizer, and clarifier are all swim-safe chemicals. Wait about 20 minutes, and you are free to swim. We suggest adding algaecide, Super Erace, and shock at night, after everyone is out of the pool.

Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient.

Pool pH will not Increase or Decrease

If it seems like you keep adding pH Increaser or pH Reducer, but it only seems to last a day (if it even has effect at all), high Total Alkalinity levels over 180 ppm may be preventing you from making an effective adjustment.

Does shock lower pH? ›

Yes, chlorine shock does affect the pH levels of the water. When chlorine is added to water, it reacts with the organic matter present, such as sweat, oils, and any urine in the pool. This chemical reaction causes the pH level to rise, making the water more alkaline.

Consequences for the pool

If the pH level is too low, the water becomes acid. This acid water can cause corrosion on the heat pump, thereby reducing its service life. The pH level of the water will also roughen the mosaic in the long term. This will put a great strain on your beautiful tiles.

Just as you can raise the pH with baking soda, you can lower pool pH with vinegar. It is not, however, the most effective additive for this purpose. You'd have to add so much vinegar, in fact, that it would raise the sugar level of the pool and become food for microbes.

Also known as “dry acid”, sodium bisulfate is a fine powder commonly used to lower the pH in pools. Sodium bisulfate is typically preferred over muriatic acid due to its safer use and ease of storage. However, as it is a powder, you should avoid using it on very windy days. The pH level of sodium bisulfate is 1.2-1.3.

Just as you can raise the pH with baking soda, you can lower pool pH with vinegar. It is not, however, the most effective additive for this purpose. You'd have to add so much vinegar, in fact, that it would raise the sugar level of the pool and become food for microbes.

High chlorine levels decrease the pH of your pool's water, making it more acidic. The more acidic the water, the higher the likelihood of corrosion. This corrosion can affect metal piping, equipment, and the surface of your pool (tiles, liners, concrete, etc.).
