Water Conditioners » pH Adjusters » pH Down

pH Down will decrease the pH in garden ponds by neutralizing excess alkalinity (carbonate hardness). This product can be used daily to adjust pH until conditions stabilize. pH Down contains no algae-promoting phosphates. It is important to accurately measure the level of pH in a pond before initiating adjustments. Use a Pond Care pH Test Kit to measure your pH weekly.

pH should be either raised or lowered by no more than 0.2 points per day. Do not treat pond water more than once every 24 hours. Plants and algae cause a temporary increase in pH in the afternoon. Therefore, pH should be tested in the early morning to obtain the most accurate reading.
