Aquarium Testing Kits
Conditions in aquarium water naturally change over time, so use aquarium test kits regularly to make sure they are healthy and stable. Master test kits include essential tests for your aquarium type - pH, hardness, ammonia, nitrite, nitrate and oxygen should be monitored in all aquariums. You may need the other test kits below during water preparation, tank setup, if medicating or experiencing excessive algae, or when keeping a planted or reef aquarium. We also carry electronic monitors to test pH, ORP and salinity.
Shop by brand or aquarium test kit type - refills and calibrators are with corresponding tests.
