API Freshwater pH Aquarium Test Kit

The API Freshwater pH Test Kit is ideal for most freshwater aquariums. It measures pH (acidity) from 6.0 to 7.6. Typically it is desirable to be as close to 7 (neutral) as possible. Certain freshwater species, such as African cichlids, will need the hi-range pH kit, as they prefer a pH level above 7.6. Easy to use, quick an accurate with up to 250 tests.
