Accurately measure ammonia to prevent fish loss. This kit is mercury-free and measures ammonia levels from 0-8ppm. Contains 130 tests and includes 2 test solutions, easy-to-read instructions, a glass test tube, and 2 colour charts. Ideal for fresh and saltwater.

Calcium Reef Kit (Ca)

Over time, calcium level drops in a reef aquarium as it is used by invertebrates or reacts with excess phosphate. Measure calcium levels as low as 20mg/L quickly and accurately with the API Calcium Ca Test Kit. Contains 2 test bottles, easy-to-read instructions, and a glass test tube.

Copper (Cu)

Monitor copper levels when medicating your pond or aquarium with the API Copper Test Kit. Easily and accurately monitor levels to maintain treatments at therapeutic levels. Tests between 0-4ppm. Ideal for use in freshwater, saltwater, and ponds. Contains 90 test and includes 1 test bottle, easy-to-read instructions, glass test tube, and colour chart.

GH + KH

Duplicate the natural habitat of your fish to prevent stress and health issues by matching their natural GH (general hardness) and KH (carbonate hardness). Contains 2 test bottles, easy-to-read instructions, and glass test tubes. Ideal for freshwater aquariums.

High Range pH

Measure pH changes in marine aquariums, African Cichlid aquariums, and alkaline tap water. The High Range pH Test Kit reads between the range of 7.4-8.8. Contains 160 tests and includes 1 test bottle, easy-to-read instructions, a glass test tube, and a colour chart.

KH

Monitor water quality and prevent invisible problems before they harm fish and plants. Carbonate hardness can be used to determine the proper dose of pH buffers. Contains 1 test bottle, easy-to-read instructions, a glass test tube, and a colour chart. Ideal for use in fresh or saltwater aquariums.

Nitrate (NO3)

Maintaining a low nitrate level greatly improves the health of livestock, while high levels can indicate a build-up of waste and organic compounds. The API Nitrate Test Kit reads between 0-160ppm. Contains 90 tests and includes 2 test solutions, easy-to-read instructions, a glass test tube, and colour chart. Ideal for fresh or saltwater aquariums.

Nitrite (NO2)

While low levels of nitrite suppress the immune system, high levels can cause suffocation for fish. The API Nitrite Test Kit can be used to read nitrite levels between 0-5ppm quickly and accurately. Contains 180 tests and includes 1 test solution, easy-to-read instructions, a glass test tube, and colour chart. Ideal for freshwater applications.

pH

Maintain healthy freshwater conditions by quickly and accurately monitoring pH using the API pH Test Kit. This kit reads between 6.0-7.6 to determine whether your pH levels are too high or low. Contains 250 tests and includes 1 test bottle, easy-to-read instructions, a glass test tube, and colour chart.

Phosphate (PO4)

Excess phosphate can contribute to algae and green water blooms in freshwater, and inhibit the growth of corals in saltwater. Monitor your levels quickly and accurately with the API Phosphate Test Kit, reading parameters between 0-10ppm. Contains 150 tests and includes 2 test solutions, easy-to-read instructions, a glass test tube, and 2 colour charts.
