D-D H2 Ocean Pro+Premium Reef Salt 6.6kg

In nature there is a natural balance between the calcium, alkalinity and magnesium levels. Many salts are found to be either unnaturally high in calcium or high in alkalinity and therefore with these salts either extra buffer or extra calcium is required to be added to return the natural balance.

With H2Ocean reef salt the calcium and alkalinity are in the correct ratios keeping the ionic balance in equilibrium with natural levels which is so important for healthy coral growth.
