If so, the AC30 will be fine. You'll just have to use a Dremel to cut down the intake pipe, turn the flow all the way down and fill it full with filter floss. If it's still too much flow, you can swap out the AC30 impeller for the AC20. I use 20s on my 3gal tanks and love them.
Yes, it is the DB 3g. How do I dremel down the intake pipe? I like to overfiltrate on all of my tanks.
