As far as sectioning off the tank, I have everything except the Aquarium sealant, I was also going to use this to make a few decorations/hidey holes, but my LFS is out! and the guy there said that it's just 100% silicone and I could pick up essentially the same thing at Home Depot.
I went there and read the back of EVERY stinkin tube, ALL said not to use below water line, or in aquariums...does this just mean it would leak? or that there is a harmful chemical in it that would harm the fish...because if its just to hold things in place, it doesn't matter if its water tight...but I don't want to poison my fishies.
Is there a certain kind I can use? I kinda need something asap, so I wouldn't have time to order online...I ended up with the first two girls of my 6 sister sorority and they are stuck in drink pitchers til this is resolved! lol
Any ideas would be great, you have all been so helpful!
