Model # P32003DE
Pool Solutions PH Minus is used to lower pH levels in swimming pool water preventing eye irritation, cloudy water, and scaling. The most important step in pool maintenance is keeping the pool water balanced.

For More Pool Chemicals
What causes scale build up in a pool? My pool walls always seem to have a build up along the water line.
Scale along the water line can be caused by high pH, alkalinity and calcium levels. I would recommend having your pool water tested and adjust the levels as needed.
My pool water is very cloudy and has algae in it so we super shocked it. Now the chlorine and pH are really high. I want to put a pH decreaser in it but we are having people over? Is it safe to swim or do we have to wait?
If the pH and chlorine are high, I would not recommend anyone swimming in the pool. The quickest way to lower both chemicals without adding more chemicals (More chemicals may add to the cloudiness) is to partially drain and refill the pool. You will want to keep everyone out of the pool until the levels are back within range.
How do I lower my total alkalinity level in my swimming pool?
You can either partially drain and refill the pool or you can use muriatic or dry acid. Both acids will also lower the pH so you will have to monitor and adjust the level accordingly.

Pros: Dissolves very quickly
This product dissolved much quicker than the more expensive product from my local pool store that I purchased earlier this year. Very easy to use great shipping and price.
