I am placing 2 maxi-jet 1200's in my 55 gallon FOWLR for flow. Since i do not want it to be creating bubbles in the tank which is the best way to install these pumps? Do i even bother attaching the air hose, or should i just plug the hole. The instructions that came with the Maxi-Jet didnt help me very much. Can anyone give me advice on how these should be put together. and maybe i'm just stupid. Thanks
