GH and KH in the Aquarium
Aquarists seek to provide a healthy aquarium environment by duplicating the water conditions of the natural habitats of their fish. Tap water rarely provides the water conditions necessary to maintain an optimal aquarium. Some tap water supplies have a very low KH level (below 3 °dKH). This type of water has very little pH buffering capacity and can contribute to wide pH swings in the aquarium. When water evaporates from the aquarium, it leaves behind hardness ions. Topping off with tap water simply adds more minerals to the aquarium, resulting in a steady increase in GH. It is therefore necessary to test the GH and KH frequently to monitor water quality and prevent stressful conditions from occurring. Use the table below to create the ideal water hardness levels for your aquarium fish. When keeping a community aquarium with a variety of tropical fish, adjust the GH and KH to 3° - 6° (50 - 100 ppm).
GH & KH RANGE - Aquarium Life
$30.00AF Nitrate TestPro is designed for quick measurement of nitrate ions in marine aquariums.
$30.00AF Phosphate TestPro is designed for quick measurement of phosphate ions in a marine aquarium. Phosphate is a breeding ground for the growth of undesired algae, so it is very important to constantly monitor its concentration in marine tanks. In addition, a high concentration of phosphate may be harmful to corals. Phosphate levels in the marine aquarium should not exceed 0.02 mg/l (ppm). This Test Kit contains sufficient reagents to perform 40 tests of phosphate concentration.
