Thanks, Jim.
Unfortunately my SPS's are not doing all that well at the moment. After re-aquascaping the rocks and corals, my huge Rose Milli (a foot across) started RTN'ing. I tried to save it by fragging a few good portions, but it was almost all gone next morning. The water fouled up and affected other SPS's. Since then a nasty chain reaction started. I lost quite a few acroporas. I still have a number of them, but some are struggling. This has been the most disappointing change that I have ever made.
Toward the end of re-aquascaping, I got shocked by a leaky current in the tank. The Sedra 3500 on ASM G2 seemed to have been the culprit. It really shocked me and all the inhabitants of 180. I don't know if this had any effect on my big milli. It was doing so well until the re-aquascaping.
Luckily, my softies, LPS's, fishes, and clam seem to be okay.
Although it's sad to lose the corals that I treasured for many months, this also gives me an excuse to go out and get more frags to fill up the void that they left when the tank settles down
