I'm considering getting a 3D background for my new 75g cichlid tank. However, I am concerned about what goes on between the background and the glass. Has anyone had one set up for a while that can share what happens back there? Does waste build up back there, should I expect an ammonia spike in the future and a tank full of dead fish? I understand there are ways to keep water flowing, but that doesn't necessarily keep it "clean" from decaying waste. Any tips?

Now that you've had your background for a while, how do you feel about it? I'm considering getting one, but I'm concerned about what goes on between the background and the glass and that there will be waste buildup back there that could cause potential danger in the future.
