Red Sea Magnesium Supplement

Magnesium is known as the glue that holds your reef together. This element is depleted slowly and can usually be maintained by regular water changes. But low magnesium can have very adverse reactions inside your reef aquarium and is very important to keep your levels within range. 

Magnesium is what helps maintain optimal levels of both ALK and CAL. With low levels of MAG this could throw off the ratios of ALK or CAL causing issues with your corals. 

Testing this element is essential to knowing how much to dose. GHI Corals keeps our systems at 1360-1460ppm. 

This product is the only magnesium buffer system GHI Corals uses on all internal systems.
