foam
This is my first post here on reef central. I don't even have a saltwater tank yet, but, I am planning on starting one soon. I keep dart frogs and many dart frog keepers, I included, have used spray foam to make backgrounds for our frog vivariums. I'll try to get some pics up sometime soon. On the last tank I did, I used a "black"(it actually cures gray)spray foam that is made for securing and sealing around rocks in outdoor ponds. I have used egg crate on prior tanks but on the last one I made, I did it a bit different. I laid the tank on it's back and laid out any rocks, or anything else that I wanted in the background on the back glass and tried to picture how I wanted it too look. After getting things in place, I I then spread silicone on the back glass(the foam alone will not stick very well) putting a little extra in places that would have rocks and such to help secure them. After smearing the silicone, I placed the rocks and such against the back glass into the silicone. After placing the rocks, I then sprayed the foam around them covering the back of the tank and making it thicker in some spots to make "rock ledges" and other features in the background. After that I let the foam cure over night. After the foam cures In my case, with frogs, I want the background to look like a dirty rock wall, I spread brown silicone over the foam and then cover the silicone with my substrate mix of cocoa fiber and peat moss. I was thinking maybe use some white silicone and crushed coral in a reef tank??
