I just finished checking out some amazing pics of various zoos around the site and I'm stumped! I have a 4x6 inch yellow and orange zoo rock that is 75% covered and it's polyps don't bloom like say...Bob's. I have them up pretty high in my tank under 180watts of PC and NO lighting. My levels are pretty good most of the time and I suppliment with trace elements and CA+.
What am I doing wrong?
