I agree, but I think your flow will be fine. To be honest, I think i need more flow in my 29g. I have a seio 620 a maxijet and the mag 7 return that also gives me pretty good flow. I am seriously thinking of getting a tunze 6060 for my 29g. I believe my tank would love it. My corals that are nearer to the seio are responding better and growing faster. Just my two cents.
