I have been thinking about doing a system like that to maximize ceiling heights. Cat witch one do you use? So you basicly use the pump in the res to top feed and the pump in the box with the timer is the pump out for waist..... Is there anything else different about the set up? I've been thinking about the sentenal the blue one..... Don't know if that spelling is good
thats the one i planned on using was the Sentinal system . i never did buy it though . i only had veg set up for Flood & drain .
