Marine Specific Test Kits

In order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness and even death. Regular testing of the water is crucial, particular with a new aquarium, in order to keep parameters like Ammonia, Nitrate, and Nitrite in check. High levels of these can cause poor fish health or death, and may be a sign the filtration is not working efficiently. Test Kits generally come in 2 different types; paper dip tests for quick simple checks and liquid test kits for a more accurate result. Marine fish and invertebrates are even more susceptible to changes in parameter levels or toxins so regularly testing is crucial.
