I have learned one important lesson in dealing with a reef tank. The more you put your hands into it, the more we usually mess it up. It’s a mini ocean, life will figure itself out. My tank has always done very well because, I for starters don’t have arms long enough to do much in my tank unless someone strings me from the ceiling, and I have a swim suit on and a snorkel. But also mainly because I keep my hands out of my tank, unless I have to put them in it. Your corals will learn how to survive if you keep your water parameters and lighting correct.
