Jebao pump decision

[thanhjenn]

I will be starting up a new tank but not sure which size pump to put in. I called /contacted a couple of retailers and got 2 different answers. I will be running a 210 gal tank (60x30x27h) with closed 3 holes. I used to run a 135g with closed loop (dart powered), 2 tunze 6100s and a return (approx 1000g per hr) for sps tank. I thought the flow is pretty good but the spread of the flow was ok on the tunzes. I'm leaning towards the rw20 on either side of the tank (corner)and dial down. Turning the power up as my tank starts to fill up (fingers crossed) but fear still be overkill? Or the rw 15s? What do you thing?

Thanks
