Hi getting a new tank this friday and also thinking of buying a 3d background, thing is ive never had one before and I cant get my head around where to put the inlet and outlet pipes as I will be running 2 external filters also 2 heaters and a wavemaker ,,,,read on internet sites some say put pipes n heaters behind background this has me confused because im guessing you silicone the edges to tank so how does this effect the flow of water and will the inllet/outlet pipes pick up the debris from front of tank and what happens if food gets stuck behind background or fish 
need help as dont want to buy one as they are expensive for a 5 ft and not know how to make the best of it
