well, i was testing out a new idea for air injection, so i built a little skimmer. the new idea didnt work, but i converted the little skimmer into a beckett just to see what would happen. what i ended up with was a beckett skimmer that has a 8" X 9" footprint (not counting the drain) and is only 25" tall. probably good for a tank under 100gal. it could also be used with a needle wheel pump instead of a beckett for about the same size tank. looks a little rough, because i just used some scraps, and the water test is with a rio 1100 - nowhere near the pump needed to get the right bubbles from a beckett injector.
