I already have the ugly filter intake tube running down in the corner (WHY does Rena make that dang thing blue??). I have the heater cord running alongside it. The tubes for the UGF are also tucked into the corners. I try to mask all of that stuff as best as possible with tall plants and rocks. My heater is actually all black and masks very well against the black background, but behind the piles of rock you cant see it at all. I have enough exposed equipment in the tank as it is.
