Either should be fine, though Iíd lean more towards the 306

I was going to say thatís too much flow but then realized I have a pair of AquaClear 50s (@200 GPH each) on my 29g. However, using the stock return outlet will provide a lot of direct flow versus the HOB output.

You lose gph on canisters once you add all the media. If I was concerned with to much flow output I'd probably run two 206's or even two 306's depending on the fish I had.
