The API pH Up 118ml is a regulator that raises the pH in your aquarium, making it more alkaline when levels drop. The pH measures the acidity or alkalinity of the water, with a value of 7.0 considered neutral. pH values above 7.0 are alkaline, while below 7.0 are acidic.

Different fish require different pH levels to stay healthy, so it's important to regularly check the water quality.

The pH Up regulator is fast-acting, colorless, and easy to use, without clouding the aquarium water. It is also phosphate and nitrate-free, preventing algae growth.
