API Test Kits

Tests tap water and freshwater aquariums for general hardness (GH) and carbonate hardness (KH). Helps detect stress on fish caused by rapid pH shifts, which result from low KH levels and helps aquarists duplicate the natural habitat of their fish.

This kit tests tap water and aquarium water for five different parameters that affect the health of freshwater fish: pH, High Range pH, Ammonia, Nitrite and Nitrate.

A complete kit for testing marine aquarium water. Tests water four ways to protect marine fish and invertebrates from dangerous water conditions.

The quick and accurate way to test pH. Tests a wide range: 6.0 – 9.0. Desiccant-lined tube, with snap-tight cap, provides maximum moisture protection for accurate results.

Ammonia Test Kit (130 Tests) Fresh & Salt Water

Fresh Water & Salt Water test kit. pH7.4 to 8.8

Measures nitrate levels in both fresh & saltwater aquariums.

Copper, a common treatment for many parasitic infections, must be monitored in an aquarium or a pond.

Toxic nitrite is produced by nitrifying bacteria in the biological filter as it breaks down ammonia. This kit tests for harmful nitrite and measures levels from 0 to 5.0 ppm.

The quick and accurate way to test for the presence of ammonia. This kit reads 0-6 ppm of ammonia. Desiccant-lined tube, with snap-tight cap, provides maximum moisture protection for accurate results.

Calcium is one of the most important elements in a reef aquarium. Reef invertebrates such as corals, crustaceans, mollusks and even some types of encrusting algae need calcium to grow and remain healthy.
