*Maintaining proper Total Alkalinity helps maintain the correct pH. Always adjust TA before trying to adjust pH. If your TA level is too high, call us for advice on how to use acid to lower it. This can be a tricky procedure and is best left up to experienced professionals to achieve good results without damaging your plaster. If pH is too high and alkalinity is correct, use an acid demand test from your test kit to determine how much acid to add to your pool. If you don't have this test, you can add 2 cups of muriatic acid per 10,000 for every tenth of a point that you need to lower pH. This is approximate. Retest pH a few hours after adding acid. Always add acid to water - never water to acid.

Proper Chemical Levels
Free Chlorine 1-3 ppm
Total Alkalinity 100-120 ppm
Calcium Hardness 200-250 ppm
pH 7.2-7.6
