Enough water flow for a 55
I've been wondering lately if I have enough water flow in my 55g aquarium. I have a fluval 405 and the output in on the upper right hand corner of the tank angle toward the front left corner, and a fluval U2 on the back left corner facing the spray bar straight to push the co2 around the tank. But lately I've been wondering if I should take the U2 out and replace it with a power head or circulation pump. What dome ou guys think. I have had bba before in this tank before I started from scratch two months ago. But not sure if more water movement would help.
What do you guys think for flow is this enough or should I replace the u2
