Lowers pH and makes aquariums more acidic. Fast-acting, colorless and easy-to-use. How much pH Down will it take to lower my pH? | The amount of pH Down required to lower the pH of aquarium 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 aquarium gravel, ornamental shells, and coral. 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. Aquarium 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 aquarium. Many aquarists treat a separate bucket of water with pH Down to adjust the pH before adding the water to the aquarium. Add as much pH Down to the bucket as necessary to lower the pH to the desired level. Once the pH has stabilized (12-24 hours), add the water to the aquarium.
| Can I use pH Down in a saltwater aquarium? | Marine salts are formulated with a large amount of carbonate buffer to stabilize the pH. Each brand has its own unique formula and pH range. While adding pH Down to a saltwater aquarium is not harmful, it should not be used to adjust pH. Use Proper pH 8.2 to adjust and stabilize pH in saltwater aquariums.
