Soft corals do not incorporate CaCO3
to grow so the Ca
levels are unimportant to them for the most part. It is however neccessary to keep the levels in a general area for proper scleractinian and coralline growth. Ca
levels in the range of 350-450 ppm
with a properly <<balanced
>> alkalinity would be fine. Higher levels will help hard corals grow aa bit faster but I would not suggest it until you have a firmer grasp on the understanding of the chemistry.
Alkalinity and KH
are not the same thing and represent different things. KH
will generally represent the total magnesium and calcium while alkalinity represents the total hardness of carbonate, bicarbonate and hydroxide. In short, alkalinity measures the water ability to resist changes in ph
>> may help some... just excuse the title.
Balanced additives are they key. Kalkwasser and two part liquids primarily. When imbalanced a good marine buffer and seperate form of CaCl
can be used but should be dosed slowly and monitored carefully until you know how the amount of each addition affects the chemistry. Golden rule, always test never guess. Water changes will also help bring the chem back into ionic balance as long as the saltmix used is properly balanced.
