A.P.I. pH Down 118ml

API® pH DOWN pH adjuster lowers pH to make freshwater aquariums more acidic for fish and plants when levels rise too high. pH is the measure of acidic or alkaline conditions in water, where a value of 7.0 corresponds to a neutral pH, pH values about 7.0 are considered alkaline, and pH values below 7.0 are considered acidic. Because it is phosphate-free and nitrate-free, pH DOWN pH adjuster will not encourage algae growth.

Determine the pH of aquarium water with an API pH Test Kit. To lower pH, add 1 ml. of 38 litres of aquarium water. Take another pH reading before adding another dose of pH DOWN.
