The room is approximately 12ft X 12ft and has 2 floor drains. One drain in the center of the room and one in the back corner where there is a shower with just a curtain. I have removed the shower head and adapted to use my one length of my python hose. I am currently running 13 aquariums. 220g (72x24x30), 100g (60x18x21), 90g (48x18x24), 2x 55g (45x12x21), and 8x 29g (30x12x18). My collection includes Africa, Asia, and S. America.
