Nano's 35g Cube

So as requested, pics of the lowest tech sump on earth its cramped so I can get great shots, also you can see, I need an ato, as the tape on the glas represents where I like my water level, and then that is 2 days evaporation.. (yikes) about 1 1/2-2 gallons)
so here you go




Last shot is side ways, (sorry) but it shows the plumbing from the return line, I have the pump sitting on a bag of filter floss to dampen sound (its silent now) and then the line goes up to a shut off valve for maintenance as well as flow control. From there it goes to gate valve (I think thats what its called) for emergency purposes, so when the power goes out the force of gravity automatically closes the line thus preventing overflow in the sump.
