Description pH (permanent hardness) is the measure of acidic or alkaline conditions in water, where a value of 7.0 corresponds to a neutral pH, pH values above 7.0 are considered alkaline, and pH values below 7.0 are considered acidic. Different fish need different pH levels to be healthy, so it is important to test your water regularly to ensure pH levels fall where they should. If water does not test at the desired pH level, use the appropriate API PROPER pH to adjust and hold the level. Use when setting up aquarium or changing water. API PROPER pH 6.5 is ideal for soft water species such as Tetra’s, Discus, and Angelfish. Additionally removes chlorine, neutralizing chloramines and detoxifies heavy metals. PROPER pH 6.5 also contains electrolytes to reduce fish stress and boost overall health.
