Calcium consumption.

[Doug]

Tony, I find kalk to keep a constant level, in an low consumption tank. I agree with your view on 2-parts. I have seen many posts on slower growth or even bleaching such as you mention, in tanks that have a problem with fluctuating calcium or alk levels. Also in my own view and from talking with someone like Rodger from Tunze, the kalk effects the pumps and equipment more than reactors. Not sure why. Rodger does not like high alk levels for his Tunze pumps tolerance levels, but I have yet to see a reactor run a tank at much less than 12dkh. Seems thats also a nice level for sps.
