Use of Tropic Marin Bio-Calcium
Bio-Calcium increases both calcium and alkalinity at the same time. Calculate the total system water volume. Each level measuring spoon will raise the calcium level of 10 US gall./36 l by approximately 28 ppm and the alkalinity by 4° KH.

Natural sea water contains approximately 410 ppm calcium and 6.5° KH alkalinity. You should not exceed a calcium level of 440 ppm and an alkalinity of 8° KH due to the possibility of super saturation and subsequent precipitation of calcium carbonate. Maximum recommended dose is one level scoop per 10 US gall./36 l of aquarium water per day.

Sprinkle one measuring spoon full of Tropic Marin Bio-Calcium onto the surface of the water, where it is being circulated by your pump. Take care not to allow a larger amount of undissolved Tropic MarinBio-Calcium to come into contact.
