Formula
Muriatic Acid (oz) = (pH Drop / 0.2) x 26 x (Volume / 10,000) | Liquid Chlorine (oz) = ppm Needed x 10 x (Volume / 10,000)
Frequently Asked Questions
What should pool pH be?
Ideal pool pH is between 7.2 and 7.6, with 7.4 being optimal. Below 7.2 is too acidic and can corrode equipment. Above 7.6 reduces chlorine effectiveness and can cause cloudy water.
How much chlorine should be in a pool?
Free chlorine should be maintained between 1 and 3 ppm (parts per million). For regular maintenance, aim for 2 ppm. Shock treatments temporarily raise chlorine to 10+ ppm to kill bacteria and algae.
How often should I test pool water?
Test chlorine and pH at least 2-3 times per week during swimming season. Test alkalinity and calcium hardness monthly. More frequent testing is needed after heavy rain, high bather loads, or extreme heat.
