I have a question about CC
and sand. I have a 125 gallon SW
about 2" deep in most places. I have read good and bad things about CC
in that it keeps the nitrates down and is a good filter BUT does trap things from time to time causing spikes. So far I have had really good luck with mine and feed VERY sparingly. I have 2 clowns, 1 yellow wrasse, 1 LM Blenny, and 1 yellow tailed damsel. I also have about 20 turbo snails and 12 hermits.
I was thinking about mixing CC
....what are your thoughts on this? And has anyone done this and to what degree of luck?
