Reef Supplements

Reef Basics Magnesium Part 3 is used in the calcification of skeletons of reef organisms. In many cases, magnesium is used in place of calcium for calcification. In addition to its role in calcification, magnesium is used by organisms ranging from bacteria, to coralline algae to...

Reef Basics Alkalinity Part 2 supplies a properly balanced (carbonate/bicarbonate) buffer system that yields an industry leading pK of 8.6 which makes pH maintenance of 8.3-8.5 easy. A higher pK increases the buffer's ability to counteract inevitable acidic sources in the water. Reef Basics Alkalinity...

Many competing buffers for reef aquaria are simply sodium bicarbonate. Such buffers have a pK of only 8.0 in saltwater and simply are unable to maintain a pH above 8.0. The low buffering pK is a function of the low carbonate/bicarbonate ratio. eight.four supplies...

Like calcium and strontium, magnesium is used in the calcification of skeletons of reef organisms. In many cases, magnesium is used in place of calcium for calcification. In addition to its role in calcification, magnesium is used by organisms ranging from bacteria, to coralline...

Iodide is a critical element for the health and formation of soft tissue in invertebrates (such as gorgonians, sarcophytons, etc). It has also been shown to be critical for the development of pigments in corals, corallimorpharia, and anemones, both the golden brown of zooxanthellae...

A frequent occurrence in reef systems is low pH, while calcium and alkalinity are at optimal levels. Raise one and the others may fall. One of the primary reasons for this is an improper carbonate/bicarbonate ratio. The buffer ratio changes as a natural consequence...
