A question about rock scaping.. I've seen some set ups where the rock is against the glass and some where it's not. Is it absolutely necessary to clean behind the rocks or is it a question of flow behind the rocks? Sorry for the newbie questions, but I'm setting up a new tank and I want the rock in the back (current tank is a peninsula set up) but I'm not sure if I should leave a couple of inches or put it right up against the glass? Any and all help is appreciated.
