ESV B-Ionic Saltwater Aquarium Magnesium (1 GAL) WYSIWYG is now reimaginedMagnesium 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.
