Powerheads for 20g fowlr

Setting up new 20g fowlr and thinking 2 hydor pico evo 400s. 100gph each on opposite sides. Good enough flow?

your going to want more than 200gph flow total in a 20g. Id recommend a minimum of 600gph total. 2 Koralia 425 nanos would be perfect for the job. More flow keeps waste suspended allowing it to be filtered or removed. Not enough flow and everything will settle, along with many dead spots.

Great thanks for the feedback. I found them on amazon for $28 each. I didn't want anything too big because of the smaller tank but they appear to be small enough

yeah ive run bigger powerheads in a 20g before so the 425's will be just fine. they are small in my opinion so shouldnt be bad size wise.
