What is pH?
pH is the measure of pond water acidity. A neutral pH reading is 7.0. A pH higher than 7.0 is alkaline, lower than 7.0 is acidic. Acid rain, mineral leaching, soil runoff decomposing plant and fish waste can cause unacceptable pH levels. Even tap water used to fill fish ponds and garden ponds can cause extreme pH levels. Avoid pH levels below 6.8, which will stress pond fish and suppress biological filter activity, and pH levels above 8.0, which will hamper the ability of most plants to absorb necessary nutrients. pH should be raised or lowered by no more than 0.5 units every 24 hours.
