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.
Pond Care 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 0.5 units every 24 hours. 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.
Directions for use: 1. Test the pH of the pond water with a Pond Care Liquid Wide Range pH Test Kit. 2. Add 1 teaspoonful (5 ml/ 5 cc) of pH Down for every 50 U.S. gallons (189 L) of pond water. 3. Wait 24 hours, then test pH. Repeat treatment as necessary.
