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)
