Why Is pH Testing Important?
Maintaining a stable pH level is essential for the biological balance of your tank. Different species require specific pH ranges to thrive; for instance, many tropical community fish prefer slightly acidic to neutral water, while marine environments require alkaline conditions. Regular testing with the Sera pH-Test helps you identify dangerous shifts before they impact your fish.
