Introduction to Swimming Pool and Hot Tub Chemistry
This article describes the chemistry involved in keeping your pool or hot tub safe and your water crystal clear.
The Relationship Between pH and Total Alkalinity
Maintaining both pH and total alkalinity in your swimming pool is important for keeping your pool properly sanitized and non-corrosive. Total alkalinity is to pH what cyanuric acid is to free chlorine. Total alkalinity stabilizes pH levels. The ideal pool pH level is 7.4 to 7.6. The ideal total alkalinity level is 80 to 120 ppm.
How to Test, Raise, and Lower Swimming Pool pH Level
You should test your pool pH level as often as you test free chlorine – about twice per week. To raise pH use borax or soda ash (aka washing soda). To lower pH use muriatic acid.
What Should pH levels be in Swimming Pools and Hot Tubs?
The ideal pH level in both swimming pools and hot tubs is 7.4 to 7.6. This is the level where water is most comfortable for swimmers while also maximizing chlorine’s sanitizing ability.
The Relationship Between Pool Chlorine and pH
The degree to which chlorine is effective in sanitizing your pool by breaking down contaminants is highly correlated to the degree to which pH is kept in balance.
In this article, we dive into the relationship between chlorine and pH, and how pH of water changes the effectiveness of chlorine.
