That neon sump distracts from the display.
All that is needed for me is Sock/Skimmer, fuge, return. Very low tech. Everything easily accessible and removable. I want to just reach in a pull out whatever it is without first having to remove something else.
Adding a built in ATO reservoir, the sump it would have to be massive to legitimize the addition of one. The display would have to be at least four foot long. Anything that wouldn’t last at least a week(7days)would be worthless. I say a week because vacation is usually that long.
