API pH Down delivers an easy to use solution for lowering the pH to the desired level in freshwater aquariums. Utilising a specially formulated phosphate-free formula pH Down is safe for fish and plants and recommended for use when setting up a new aquarium, adjusting pH, or changing water. pH in an aquarium can fluctuate due to fish waste, uneaten food and addition of tap water. It is recommended to test water for pH weekly.

What Is pH & Why Does It Matter In Your Aquarium?

pH is the measure of acidity of water, on a scale ranging from 0 to 14. A pH of 0 is the most acidic, while a pH of 14 is the most alkaline. Different geographies have different tap water conditions with different pH levels, while certain fish species require a specific pH level to thrive. A pH of 7.0 is ideal when keeping a community aquarium containing a variety of tropical fish. Goldfish and livebearers prefer a pH of 7.5. Many Amazonian fish, like angelfish and neon tetras, prefer a lower pH around 6.5 to 6.8. Mollies and swordtails thrive at pH 7.2 to 7.5.

How To Use API pH Down?

Test your aquarium water with a suitable pH test kit. To lower the pH, add 1ml of pH Down per 38 litres of water. Retest before adding another dose. Some fish are sensitive to pH changes greater than 0.2 within 24 hours, so adjust carefully. Check pH weekly and use pH Down only when needed.

Tip: Mineral-rich water can resist pH changes or cause pH to rise again after treatment known as “pH rebound”. Repeat doses may be needed, but always retest before dosing.
