Shelley, I don't think it was the swap that was the problem, I"ve done it many times before. I think it was the sitting around in rubbermaid totes at 18C that did the job. The corals just got too cold and reacclimating them to normal temperatures just didn't go all that well.
Marie, sadly the 180 isn't going to be ready for quite some time. Apprently we need a sub panel and part of our heat pump whatevery system has to be moved. I'm away for 2 weeks this month and my husband is gone next month.

I think we're looking at almost october before it even sees water
I'm brewing up some water right now for a water change. Oddly enough, I have every test kit but an ammonia one, how stupid is that.
My tank doesn't have any sand and hasn't for some time. There was a lot of "detritus" on the bottom of the tank when I took out the rock so I wouldn't doubt that some of the cloudiness might be it getting stirred up but I suspect its the corals that are making the water cloudy. The water was pretty cold yesterday and I'm sure they weren't happy.
