So where was I? :wtf: Oh yeah... more pics so you can see what I have done to put this thing together. I used 2 of the 10 in airstones and some vinyl tubing attached to an air pump to drive the bubbler. I drilled holes at the top of the container so that I don't have to worry about leaks. Also I cut the tubing at an angle (pic 2) to make it easier to feed thru the hole. Once inside I cut it squared off (pic 1) before attaching to the air stones.
