I wanted to throw out there a discussion on a crash that I had that I may have been able to prevent. In planning my upgrade from my 28 to my 45 cube I had started curing rock in my grow-out system for several months (I have a separate 20t plumbed in with just rock mud and sand but there is also a smaller fuge area with some rock and the macro). In that time I also started accumulating frags for the new tank and storing them in my grow-out system. Everything was doing great and growing well in the frag tank and the NC28. When it was time to fill the 45, I got the sand in and then just started pulling rock from the mineral fuge and putting it in the 45. I believe that was my first mistake. I did not appropriately account for the reduction in surface area based on the livestock I had added to the system. I intended to replace the rock with that from the 28 that did not go over to the 45, but stirring everything up and pulling all of the live rock upset the system and everything in the grow-out started to look very unhappy. In a panic I moved everything over to the 45 because I thought something bad had gotten into the tank (still not realizing the impact of the removal of rock). In the 45 I had the lights too high for the corals that were under t5s in the frag tank and further compounded the issue with bleaching. Unfortunately I realized all of this too late, but simply turning the lights to 50% and slowly ramping from there seems to have completely undone the entire issue. I have great PE again and some of the bleached corals have started to come back very well. Unfortunately, my mistake cost the the lives of 6 sps frags and seriously damaged several others. Live and learn I guess, but I want to make sure there isn't something else that I am not considering and I want this out there for anyone else about to make the same mistakes I did.
