Holy Upside Down Tank, Batman!!

Cool tank. The air just recirculates from the top i think because if you get too much air in the top tank then the water level will slowly start to fall... cool idea, but if for some reason you get an air leak in the top tank you are going to have quite them mess.. even if you get too much air up there you could get an overflow from the bottom tank.. i have enough trouble with water levels and maintenance on a normal tank ><

 

how in the hell do you clean that thing
