Product details
ME Coral Magnesium Powder is a salt & additive magnesium (Mg) supplement designed to help maintain stable magnesium levels in marine aquariums. It comes as a powder that is pre-measured to make a half gallon liquid solution when mixed with RODI water, making it practical for consistent dosing. Magnesium is important because it helps calcium (Ca) and alkalinity (KH) interact properly; when magnesium is low, Ca and KH can become harder to maintain and may precipitate out, leading to a need to increase Ca and KH. Use it alongside your magnesium testing routine and, for best results, with ME Coral Calcium and Alkalinity products.
Features:
- Pre-measured powder for mixing a half gallon liquid solution with RODI water
- Pharmaceutical grade USP magnesium chloride hexahydrate and magnesium sulfate anhydrous
- Ammonia, phosphate, nitrate and bromide free
- Dissolves quickly to form a crystal clear solution with no residue or impurities on the bottom
- Helps support balanced aquarium chemistry by promoting proper Ca and KH interaction
