How does that ATO work? Is it actually a sump? I just noticed the switch is toward the bottom of that little acrylic enclosure.

It is a C-Level Top off. I bought it as a complete system, but have done a little modding to it. I am upgrading the pump to accomidate the 4 foot of head pressure. It is a little pump now. I am putting a Maxi900 on it. The float switch in there is for shutting off the pump if the Reservoir goes empty. That way you don't burn it up. I am also putting together some piping to go up the back of the nano and make a 180 hook into the return pump section. I will post some picks when done tomorrow.
