so now im building a room within the garage wich gives me a reason to make new racks that hold more tanks. room will be 11x22. glad the only car i park in there is my bug and ill have to park it at an angle after room is built. what are good pumps that i can run plumbing off of? ill have 18 20s on 1 wall. and 12 60s on the other. ill have a 6x2x2 and 5x2x18 on end walls. also any ideas on floor coatings that arent as cold as concrete? im looking at a solar heater to cut costs durring the day. anyone have a diagram of a central plumbing system? i need some ideas, what size bulkheads for exit? oh and i need a huge airpump! first time building anything like this. all my tanks have heaters, filters, powerheads....
