I've put together an air loop for a my fish room, but have a question before I determine the final positioning of the air pump. Right now it would be very difficult to mount it near the ceiling. I would like to mount it about mid-way up the wall, with 3/4" tube hooking into the the air loop near the ceiling.
My one question about this setup is whether or not I need to put a check valve in-line for every drop, or is there a solution where I can use some sort of larger check valve between the pump and where air goes in the loop?
