Do I need another powerhead?

[aKlevans]

Hey everybody,
I have one Koralia nano 425 in my 40 breeder. I also have a Seachem Tidal Power Filter 55 providing some flow.

My question is, do you think I need another powerhead or is my flow already strong enough?

Yeah, i think youll want quite a bit more than that. I wouldnt count the power filter really at all and add at least another koralia 850 or two 425's in a 3 foot tank.
