Foam rubber background
Granted, its late as hell now, but just so i know what to expect....
I made a 3d background out of a sheet of foam padding i had. I burnt the crevaces into it myself, as well as made sure there were no small pieces that could flake off. Its not sealed or anything. And its secured via silicone to the bottom and back of the tank.
Have i made a horrible mistake and if so, what all have i done wrong and why?
I dont believe its toxic, nor does it flake or particle off. And it does not interfere with the water intake of the filter.
Any advice is welcome and wanted. Thank you!
