So I'm building my 3d background for my 55 gallon freshwater tank, I'm getting to the point where I'm going to start water curing it but how do people who have build these get them to sink haha. It is made out of syrofoam. I have one more coat of quickcrete to do this afternoon and them seal it. Any help would be very grateful seeing how I've spent a lot of time on this. Cheers
