Alkalinity (Kh) along with Calcium (Ca) gets consumed by corals on a daily basis. This consumption needs to be replaced. Target range for Kh is 8-10 dkh. Test often with a quality test kit. It is important to keep Kh as stable (without big fluctuation) as possible. This is why Kh is typically used along with Ca as part of a 2-part dosing system. Kh and Ca can be dosed manually, if done in small amounts while monitoring your systems Ph level. MeCoral Kh is designed to raise Ph.
