I have a fan pointed at the floor where the tank was as well as a dehumifier and strong fan in the basement pointed up. I estimate that less than a half gallon leaked out, but it definitely went under the wood floorboards and leaked into the insulation. I will be working in the basement to take the insulation down after work today. Worst case is that I just replace a bit of insulation, but I want it to be dry. So far, there doesn't seem to be much damage to the floor. A couple spots where the seams are on the boards look slightly swelled, but it's not that big of a deal. I am mostly worried about the water in the insulation causing mold to grow.
The corals and inverts are in the frag tank. The funny thing is that I was planning to take the frag tank down and sell it later this week at the local frag swap. I've not had the time to really devote to keeping the parameters ideal, so it has been neglected. Now, I did a almost 100% water change with tank water and will be dosing to try to keep the frags and colonies happy. We will see.
I sent an email to IM to see what they can do for me. It's out of the warranty period, but I still trust their tanks enough to get it another shot. I am thinking about getting a 75 ext this time. I want a little more room and depth so keep some fish that require larger tanks, possibly an anthias. The bummer is that it looks like I won't get the new tank until December or January due to them selling all their stock with the recent Black Friday sales. If I don't go with another, I honestly have no idea what tank I will get. Possibly an UNS? Their stands are metal (a must for me) and have some excellent features. The tanks look pretty well made with the mitered corners too. I would really like to get a NYOS tank, but I will never not have a metal stand for an aquarium.
