The tank is cycled right?
Just a question I'm not sure if you stated that...You said if there is any ammonia reading than you do a water change? That is great that you do that but that means your tank isnt cycled yet. Just keep doing what your doing, I would do a test every day and if there is any ammonia do an immediate water change. Regarding the marbles, I guess its fine, I mean, gravel would of been much better, but if you can keep up on the cleaning then it should be good. The only problem I amseeing with marbles is that I dont see how beneficial bacteria colonies can form in the marbles. They are spaced and everything, and when do a gravel vac it gets the poop but I'm a little IFFY on that. If you could I would definetly switch to gravel.
About the background, are you stating that you are trying to put stuff ( like fake plants ) behind the tank? I think that if you go to the LFS you could buy some background, they have fake plant backgrounds. But I think just plain black or even a blue give's it a more natural look. Hope this helps!
