Red Sea Foundation Calcium+ is a balanced supplement designed to aid the building of robust coral skeletons.

It uses a formula of Calcium, Magnesium, Strontium and Carbonate to promote healthy coral growth and ensure that the corals always have the perfect levels of each essential element. Corals use all of these components to build a strong skeleton and overall vitality, so in a busy reef tank they are naturally depleted. Topping up with this excellent supplement will ensure that your aquarium is always at its very best.

Each pack contains full instruction towards dosing schedules and amounts.

This supplement is recommended for aquariums up to 500 litres (125 gallons).

Liquid supplement: 1ml will raise the Ca level of 100 litres (25 gal) by 2ppm.
