API pH Down Size:4oz increases the ambient air temperatureAPI pH DOWN 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. Recommendations Determine the pH of aquarium water with an API pH TEST KIT. To lower pH, add 1 ml. for each 10 gallons of aquarium water.
