Pond Logic pH Drop, 16 oz.

Why should I use pH Drop

• Extreme pH levels must be avoided for the health of your pond
• A pH range between 6.8 and 8.0 is ideal for garden ponds
• Acid rain, mineral leaching, soil runoff, and decomposing plant and fish waste can cause unacceptable pH levels to occur
• Plants and algae cause a temporary increase in pH in the afternoon. Therefore, pH should be tested in the morning to obtain most accurate reading

How much pH Drop will it take to lower my pH?
The amount of pH Drop 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 Drop neutralizes some of the carbonate hardness. It may take several doses of pH Drop to neutralize enough carbonate hardness to lower the pH.

Why does my pH level drop after adding pH Drop 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 Drop contain phosphates?
No. pH Drop contains no phosphoric acid or phosphates.

Purpose and Benefits
pH is the measure of the acidity in pond water. A pH reading of 7.0 is neutral, a pH higher than 7.0 is alkaline, and lower than 7.0 is acidic. Acid rain, mineral leaching, soil runoff and decomposing plant and fish waste can alter the pH and cause unacceptable levels. Some sources of tap water used to fill ponds can also cause extreme pH levels. A pH below 6.8 or above 8.0 should be avoided. A pH level of 7.0 to 7.5 is ideal. pH levels of less than 6.8 can stress pond fish and suppress the activity of the biological filter. A high pH of more than 8.0 will limit the ability of many plants to absorb necessary nutrients. Pond Logic pH Drop 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 Drop contains no algae-promoting phosphates. It is important to accurately measure the level of pH in a pond before initiating adjustments. Use a pH Pond 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.
