Reactors and Additives

Victor,

I doubt the small amount of algea in your system could even put a dent in the alk.
A low Calcium is probably(believe it or not)is one of the parameters i least concern myself with.
Alk being at the top of the scale.
Having said that i cannot explain the chemistry involved but i could say that a low alk and a high calcium is probably much more of a concern than the reverse,IME.
When tested(albiet never [img]images/smiles/icon_wink.gif[/img] ),my calcium reads only in the neighborhood of 375-400+/-,yet my Sps thrive.....i think maintaining high alkalinity allows sps to metabolize(?)all elements more efficiently.
In the past,when i used buffers it was totally the reverse....with kalk/buffers i could maintain calcium but not a decent alk,this resulted in a MUCH(like probably 3-4X) slower growth rate aswell as a loss of good color.

At this point if anything i would even increase my alk higher and loose abit more calcium.

Of course its JMVHO though,Marc.
