LR against the back wall

[azreefgirl]

I've noticed a lot of nano tank owners have your LR up against the back wall. I'm rearranging my LR tonight (after replacing my leaking tank!), and I'm just wondering if anyone has any problems with keeping things clean behind the rock, or is cleaning even an issue? Am I going to find a disgusting wasteland behind those rocks if I rearrange things in the tank? Do critters go back behind the rocks to die and then rot? :notsure: I do have a small Rio 50 that I can put in there to get some flow behind the rocks.
Any advice would be appreciated! :happyfish

flow is always good behind the rock wall also you might just wana 1-2 times a week just grab your powerhead and blow all your rocks on and the ground lightly that will help with the build up of waist
