API PH Down Freshwater Aquarium Water Treatment 120ml

The pH of a liquid refers to it’s level of acidity and whilst fish can tolerate small changes in the acidity of the water they call home, it’s important to regularly check how the build up of organic material is affecting the water in your aquarium. The role of API’s pH Down is to lower the pH level of the water to one that allows your fish to thrive and live a healthy life.

Before using this product, make sure you have tested it with API’s pH Test.

Check pH level before dosing again.
