So I did pick one of these units up and it didn't take long to set up. All you need is a reservoir, a pump, and some tubing. The JBJ system only comes with the controller, 2 float valves, and some brackets. I set up a spare 20g tank I had beside my main tank. In that tank I put one float valve and a maxijet 900 pump. The other float valve is set up in the sump at the level I want to keep the water at. There is a couple feet of 1/2 inch vinyl tubing going from the maxijet to the sump. The controller is plugged in and then the maxijet is plugged into the controller. When the float valve in the sump drops the maxijet turns on and fills the sump until the valve comes back up. The float valve in the 20g tank is there so that if the reservoir runs out of water the pump won't turn on. It all works very well, I'm quite happy with it. If you want some pics of my set up I can take some and PM them to you when I get a chance.
