Hmmm... hadn't thought about the silicone. I'll have to check it. I think I can repair it easily enough if it leaks.
I have discovered that a good source of water may be an issue. I'm currently looking into it. Due to this I think I'm going to have to do a FOWLR system, although I intend to set it up the same way I would for a reef system (sump, refugium, etc) and maybe I can convert it later. I may end up buying distilled water from walmart for a while.
Thanks, everyone. I'll see what I come up with.
