Salifert Coral Calcium 250 mL Information

Product Manuals & Documentation

Why is calcium required?
Calcium is a major constituent of calcareous algae, skeletal material of hard corals and the skeletal needles of soft/leather corals.

Calcium also fulfils many biological functions. These processes result in depletion of calcium.

Quite often a too low calcium concentration retards growth of corals and calcareous algae.

NSW (Natural Sea Water) contains 400 - 450 mg/L calcium.

This is also the value we should strive for. For a stable aquarium environment the fluctuation in calcium content should not be more than approx. 15 mg/L.

About Coral Calcium
We have highly concentrated this supplement. In fact a higher concentration is impossible to achieve. Each liter contains approx. 160,000 mg of calcium. You will appreciate this when you consider that an average aquarium depletes 5-8 mg of calcium per liter, each week.

To avoid an ionic imbalance, we properly balance the calcium with ions such as sulfate, chloride, bromide, sodium and magnesium.

All ingredients are of a pharmaceutical quality or even better. This ensures that no unwanted elements are added to your valuable aquarium.

Right after you have dosed this supplement the calcium is immediately for the full 100% available to your corals and other calcium requiring organisms.

Other requirements
If calcium is depleted because of growth of corals and coralline algae then supplements such as Salifert’s KH+pH Buffer and Strontium are also required. Since they form together with calcium the major ingredients of shells, coralline algae and the skeletal material of corals.

Shake before use.

Regular maintenance:
Dose 5 ml per 100 liters (25 gallons) once a week or two weeks.

Adjust dosage according to individual requirements (use a calcium test, e.g., Salifert’s Calcium Profi-Test). Every 5 ml per 100 liters (25 gallons) will increase the calcium concentration by approx. 8 mg/L (8 ppm).

Never increase the calcium concentration by more than 50 mg/L a day. Maintain a calcium concentration of 400 - 450 mg/L.

Keep out of reach of children. In case of contact with eyes rinse with plenty of water. Only for aquarium-hobby use. Not for human consumption (directly or indirectly)!

Manufacturer Info

Salifert is a Holland base company that produces top of the line test kits as well as tank additives and foods for marine and reef aquariums.

Comments: Love this stuff, I have tried many other(if not all) Calcium supplements on the market and they just never seem to raise the Ca level in my tank to the 425ppm level I need for my heavily stocked LPS reef.Can't get my local store to carry Salifert so I order it here. Thanks Marine Depot. One week of dosing with this stuff and BOOM my Ca is exactly where I want it.... Short of adding a Ca Reactor nothing better than Salifert Calcium Supplement for a reef tank.
