- Contains all 70 trace elements found in natural sea water
- No unnatural by-products
- Exact dosages without prior dissolving
- Will not alter pH of aquarium water when used as directed
- Without phosphates and other pollutants
How to use: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 Bio-Calcium to come into contact with invertebrates. Add the supplement slowly, to avoid a clouding from localised super saturation.
