Aquarium Pharmaceuticals Aquarian Freshwater Gh Kh Test Kit

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.KH amp GH Test InstructionsWhat is Carbonate Hardness KHCarbonate hardness also known as alkalinity is the measure of carbonate CO32 and bicarbonate HCO3 ion concentrations dissolved in water. These minerals are present in municipal, well, and bottled spring water. The level of carbonate hardness in tap and bottled water depends on the source of the water and the treatment processes it has undergone. Carbonate hardness helps stabilize pH in the aquarium. An aquarium with a low KH level 50 ppm or less will tend to be acidic. Aquariums with very low KH are subject to rapid pH shifts, if not monitored carefully. Water with a high KH level 200 ppm usually has a high pH. The Aquarium Pharmaceuticals KH Carbonate Hardness Test measures KH in German degrees °dKH. To convert °dKH to parts per million ppm, multiply °dKH x 17.9.Directions for Testing Carbonate Hardness KH Read thoroughly before testing. Do not allow Test Solutions to get into aquarium. To remove childproof safety cap With one hand, push red tab left with thumb while unscrewing cap with free hand. Rinse a clean test tube with water to be tested. Fill the test tube with 5 ml of aquarium water to the line on the test tube. Add Carbonate Hardness Test Solution, one drop at a time, holding dropper bottle upside down in a completely vertical position to assure uniformity of drops. After first drop is added, solution will turn blue. If the water sample contains only 1°dKH, the solution will turn from clear to its yellow endpoint after the first drop is added. Cap the test tube and invert several times after each drop. Keep count of... Read More
