API pH Up

API® pH UP® is a fast-acting pH adjuster designed to raise aquarium pH levels when water becomes too acidic. By increasing alkalinity, it helps create a stable, healthy environment tailored to the needs of your fish.
pH measures how acidic or alkaline water is on a scale where 7.0 is neutral. Values below 7.0 are acidic, while values above 7.0 are alkaline. Because different fish species require specific pH ranges to thrive, regular water testing is essential for maintaining proper conditions.
