How much pH Down will it take to lower my pH?
The amount of pH Down required to lower the pH of pond water depends on several factors. The primary cause of high pH is an elevated carbonate hardness (KH) level. Carbonate hardness, also known as alkalinity, is found in tap water and may also leach from soil. Each dose of pH Down neutralizes some of the carbonate hardness. It may take several doses of pH Down to neutralize enough carbonate hardness to lower the pH.
Why does my pH level drop after adding pH Down then bounce back up the next day?
pH rebound occurs when the carbonate hardness is high. Pond water with high carbonate hardness resists pH change.
Does pH Down contain phosphates?
No. pH Down contains no phosphoric acid or phosphates.
Can I add more than the recommended dose of pH Down?
Always follow the directions when using pH Down in the pond.
