pH Down & Up - Pond Care

pH Down

Slowly lower the pH of pond water (making it more acidic) without harming delicate pond fish or aquatic plants. Slowly neutralizes alkaline substances that cause high pH (pH of pond water is affected by mineral leaching, soil runoff & decomposing waste). A high pH limits the ability of aquatic plants to absorb necessary nutrients. Contains no algae-promoting phosphates.

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.

pH Up

Slowly raises the pH of pond water (making it more alkaline) without harming delicate pond fish or aquatic plants. Slowly neutralizes acid substances that cause low pH (pH of pond water is affected by mineral leaching, soil runoff & decomposing waste). A low pH can stress pond fish & suppress the activity of the biological filter. Contains no algae-promoting phosphates.

The amount of pH Up required to raise the pH of pond water depends on several factors. The primary cause of low pH is a low carbonate hardness (KH) level. Carbonate hardness, also known as alkalinity, is found in tap water and may also leach from soil. If the carbonate hardness level is low, pH will tend to drop over time or fluctuate up and down. Natural acids also lower the pH. Each dose of pH Up neutralizes some of the acid and raise pH. It may take several doses of pH Up to adjust the pH.
