An agent to maintain constant carbonate hardness in coral reef aquaria. Dissolve 80 g of the product in 1000 ml of deionized water. To maintain ion equilibrium, use Calcium, Magnesium and Reef Mineral Salt Aquaforest products as well. 10g KH Buffer increases by about 3,3 dKH (Alk. 1,18meg/l) in 100L. 100ml KH Buffer solution increases by about 1,60 dKH in 100L of water. The recommended KH level in coral reef aquaria is 6.5- 8.0 dKH. Contains NaHCO3. US: Dissolve 1.28 cups of the product in 1 US gal. of deionized water.
