I've had this vertical 10 setup for a good three months now, and it's my first one. There's been places where there wasn't enough silicone on the great stuff so the cocoa fiber didn't stick. Now I have sporratic places where you can see the great stuff. It kind of looks like a rock or something. I'm just worried about it harming my frogs in any way. I don't have any in there yet, so it's no big hurry. The door is made out of acrylic and i'm having trouble with warping, too. Should I just make a new tank or will the great stuff be fine? I heard about it being toxic when in contact with water, but it's been setup for a while now. Any suggestions?
