3D bkground for reef tank?
I've seen a lot of posts on here about the 3d backgrounds for freshwater tanks, but not a reef tank (at least that I've seen).
Other than the basics, do I need to do anything special?
Some kind of sealant I should put on after doing the cement?
A totally different method?
Also, I found some decorations at hobby lobby that I know aren't safe...is there some kind of sealant I can use on those to make them safe?
I will keep you guys updated if I can figure out the little things, I already have the styrofoam set up how I want it =)
