Fritz RPM Elements Part 2 Calcium 473ml / 16oz

It is impossible to maintain a healthy, vibrant marine aquarium without also maintaining the proper levels of calcium and alkalinity.

FRITZ RPM CALCIUM/BUFFER SYSTEM allows aquarists to maintain these two critical components in their proper ionic balance. Unlike other similar products, FRITZ CALCIUM/BUFFER BALANCE does not contain unmeasured and unnecessary ions and metals, which unchecked can lead to toxicity in the aquarium.

PART 2 is formulated to provide the highest purity calcium, and when used in conjunction with PART 1 along with regular water changes with a high quality salt like FRITZ RPM SALT it will provide the correct ionic balance necessary for healthy and beautiful coral, fish and invertebrates. Guaranteed Analysis: Calcium (min) 55,000 ppm Ingredients: Deionized water, Calcium chloride
