COMPLETE - Balanced Calcium and Alkalinity Supplement, 64 oz

Complete is a balanced two-part calcium and alkalinity supplement. It is formulated to help maintain and stabilize calcium, alkalinity and pH levels in your aquarium. With the inclusion of numerous trace elements, this formulation will help to boost the growth of your corals and ensure the health of your aquaria.

Calcium is an essential component of many corals’ building structures. Without calcium, many corals and other calcareous invertebrates will not survive. Even some soft corals require calcium to help build their sclerites: which are responsible in helping them to maintain their shape. It is important to keep the calcium level in a reef tank between 380ppm and 450ppm.

Having a consistent and high alkalinity level will help to buffer pH and help improve coral growth. The buffering capabilities of Cal-Alk Complete will help to maintain your aquarium pH between 8.0 and 8.4: which is the ideal level for your tank inhabitants. It also provides the necessary carbonate ions for healthy coral growth. The ideal alkalinity level is 3.0 meq/L to 4.0 meq/L.

Contains no nitrates or phosphates!
