Thanks for the good luck!
I'm hoping we'll have no more problems for the future. We've opted not to add any fish like I mentioned earlier for a little while. Probably at least a couple of weeks to get our chemistry straightened out, our reactors online, and our new sump in place.
The flooding was a fluke, a combination of faulty choices, that is almost impossible to see now with the fan running. The fish deaths, particularly the angel, like someone on RC pointed out, can also be a fluke. Sometimes some fish just keel over, and it could be any reason.
I have a few things to do over the next couple of weeks, and then maybe once the lighting, sump, and reactors are online we will revisit the idea of adding new fish to our set up.
