with your current spot trust me i think a decent size CUC can live off whats in those photos.I think I vaguely remember a BRS video saying that too much CUC can cause the CUC to die from starvation further leading you into having more PO4 and nitrate problems, causing you to think you need more CUC, and the cycle goes on. Don't hold me to it, but that's at least what I remember.
Tank is (after the home move) a red sea 625 xl - so 135 gallons. Used to be a 90 for the other 5 1/2 years. Fish are:
- Mag foxface
- Chromis
- Two clownfish
- Scopas tang
What CUC do you have and what species?
