What GS Foam?

[brp4e.]

I am going to be making my rockwall fairly soon for my exo terra tank and i wanted to know which great stuff foam i should use.. i have the big gap filler right now, is that one allright?

big gap and gaps and cracks are both fine, as well as the pond type, but the flexible one for windows and doors should be avoided. if you decide to use the pond foam, check your local Ace hardware store, the one here has it for 10.50 per can, and that's the regular price. another thing to note is that if you plan to do extensive carving, you should go with gaps and cracks over the big gap filler, because the big gap filler will have larger voids inside. one more thing i discovered recently, prepping the surface of that foam with drywall sandpaper (it's basically mesh coated with fine sand) greatly improves the adhesion of any covering material, does not clog like normal sandpaper, and can be used to carve in place of a knife. have fun, and good luck!

im actually going to spray the foam onto eggcrate and then cover it with habacrete, ill have to return my big gap filler and get the gaps and cracks one cause i want to carve some ridges in it then sand it so it wouldnt't be like super flat. thx for the tip.

Hi all, new to the site and looking to start a vivarium. I use to have a Golden Gecko, and housed him in a Exo terra tank with the fake foam rock wall. I am wanting to convert that tank and a 44 gal Pentagon, in the Pent i wanna do both small fish( neon tetras or sorts) and wondering what kind of filter or pump I could use to clean the water and use to make a waterfall as well?
