Salifert Coral Calcium 1000ml

Product description Quite often too low a calcium concentration retards the growth of corals and calcareous algae. Natural seawater contains 420-450 mg/L calcium and this is also the value we should strive for in a stable aquarium where the fluctuation in calcium content should not be more than approximately 15 mg/L. The addition of Coral Calcium immediately makes 100% calcium available to your corals and other calcium-requiring organisms. If calcium is depleted because of the growth of corals and coralline algae then supplements such as Salifert's KH+pH Buffer and Strontium are also required. Since, together with calcium, they form the major ingredients of shells, coralline algae and the skeletal material of coral. Directions Shake well before use. For regular maintenance, dose 5ml per 100lts once a week. Adjust dosage according to individual requirements using an accurate Calcium test kit. Every 5ml of Coral Calcium will increase the calcium of 100lts by 8mg/l (ppm). Never increase the calcium concentration by more than 50mg/l a day. Maintain calcium concentrations of 420 to 450 mg/l.
