Hello. I want to make a background for my T out of Styrofoam + dry coco fiber. Can I use aquarium silicone on the foam or will it melt/mess it up?

Yes, you can (and should) use aquarium silicone.

I'd be wary of using regular styrofoam (like from a tv box)

You can use aquarium safe silicone, avoid any kind of super glue, because it melts the styrofoam.

You can use PU foam too, but I'd paint the glass before aplying the polyurethane foam.

I did mine out of PU foam.


You can cover the entire foam with topsoil or coco fiber like stuff

Definitely visit the dendroboard web site. They have this down to a science

I would go with the spray foam. Either Great Stuff in the red can or if you can find it there is a foam people use on fish ponds. That foam is black, so if you miss filling in an area it's not as noticeable.

I've always used Titebond 2 or Titebond 3 wood glue. It's food grade, so safe for animals and it cures quicker than silicone.

I put my foam on in a THIN layer because it expands. You can stick cork bark in the foam for a different texture or more natural look. Give it 24-48 hours to cure. You can carve it if you like to make it more even.

Then I spread a decent layer of glue on the background using a 1 inch paint brush, working a section at a time. Press coco fiber or peat moss into the glue. Smash it in there to get it in the glue. Coco is easier to work with, less dust too. Let that dry for 24 hours then go back and touch up the bare spots.
It's really easy.

Tomorrow I'll get on my PC and post some photos of the entire process start to finish. Don't have those pics on my phone.
Hope that helps buddy.

@Braden I didn't have as many good pics as I thought. But here's what a Great Stuff background looks like under construction. Because this was a dart frog vivarium I included net pots for plants incorporated into the backgound. 100_2900.JPG

WOW! That is absolutely stunning!


However you might want to rethink styrofoam. Apparently it can leach chemicals and is am endocrine disruptors.
OK! Here is the stuff I got, look right?

They look awesome! Are you going to add a front grill? It will increase the ventilation dramatically.

Regarding to the background, I'd put a black adhesive film or paint the glass before spraying the foam. It will give you a better look, and in the case that you need to remove the background it will be much easier to clean the glass.
