Magnesion is a highly-concentrated magnesium supplement designed to maintain optimal magnesium levels in marine reef aquariums. This vital element helps regulate the balance between calcium and carbonate concentrations, preventing unwanted precipitation that can deplete these essential components. By ensuring proper magnesium levels, Magnesion supports the healthy growth of corals, clams, and other calcifying organisms, which rely on magnesium for their skeletal formation. Formulated by a marine scientist, this supplement is free from unnecessary organic materials like EDTA or gluconate, making it a reliable choice for reef hobbyists looking to maintain stable water chemistry without introducing unwanted substances.
