Extra Calcium: Highly concentrated Calcium supplement
In reef aquaria, maintaining calcium within a range of 412 - 450 ppm will enable corals and other reef-building invertebrates to grow rapidly when all other physical and chemical requirements are met. Extra Calcium is a very efficient Calcium additive Manufactured from pure laboratory grade salts designed to rapidly restore Calcium concentration to NSW levels. A perfect additive to be used also in Balling Method in combination with Extra Magnesium, KH+ and our line of Trace Elements.
Use: add every other day or as needed to maintain the calcium concentration within a range of 412 - 450 ppm. It is suggested to create a stock solution by dissolving 10 grams (~5 teaspoons) of Extra Calcium in 0,2 lt (~6,76-fl. oz.) of RO water; each ml of the solution will increase the calcium concentration in 5 lt (1,32 US-gal) of water by 2.0 ppm.
