I don't quite agree with the calcium part of the blue coral method, as there is no scientific evidence of calcium levels above 360ppm increase calcification, its more about having the reserve .Fact! The alk part, yes absolutely,fact, the feeding part, absolutely Fact! The hgh part, ...............High calcium and alk levels will boost growth
why the need for the fast growth rate?
The growth forms of corals may change dramatically in aquariums often
making them unrecognizable even to coral taxonomists (Carden Wallace and
John Veron, personal communications).
Corals may also grow in unusual directions, or the polyps may extend well
beyond the corallum (coral taxonomists are often unable to identify aquarium grown corals).
2. The skeletal density of corals in the aquarium may be significantly less than their wild counterparts, and in some circumstances may by so soft that it crumbles when touched...................
A similar test was conducted on specimens
of A. pulchra from Tumon Bay,
Guam. Specimens collected from Tumon
Bay had a density of 1.23 g cc~', but after
six years in captivity at the Waikiki Aquarium,
the cultured coral had a density of 0.81
Irie if you look at how that specific hgh works the high Ca levels makes sense, it is about having reserve Ca for the increase in cell activity in this case calcification.
I want to try the blue method but I'm not comfy using the hgh.
