Well, my 20GH is now a heavily planted setup and my Whisper 20 + 10 setup and just can't keep up anymore. Not enough flow, not enough filtration. I was thinking about a small canister setup. What are you plant guys running on yours?
Use a net and skim it off. I would think a Aquaclear 50 (hob) would be more than enough for that tank. If you want a cannister get a Rena XP1. I use one on my 29, does a nice job.
If you want a small canister I use a Fluval 204 on my 29 what a difference. I also use a cascade 700 works well on another 29 I have. cascade is the cheapest. around $80 shipped.
