Calcium 850g (Balling)

This Aquaforest product is a calcium supplement for reef aquariums that need calcium levels held steady between water changes. It is intended for reef keepers who dose calcium by the Balling method and want a CaCl2-based source with a recommended target of 400–440 mg/l.

Why it matters

• The active ingredient is CaCl2, the calcium source the product is built around.
• The recommended calcium level for the aquarium is 400–440 mg/l, which sets the target the dosing is meant to maintain.
• The Balling method calls for dissolving 50 g of this product together with 10 g of Magnesium Aquaforest in 1000 ml of demineralized water, so the dosing solution is prepared at a fixed ratio.
• The manufacturer states that ionic balance also requires Kh buffer and Reef Mineral Salt Aquaforest, so the supplement is meant to be used as part of a set.
