Powerhead 38g?

[mainereefer]

So I'm setting up a 38g bow front
No sump, fluval canister filter with scwd on return
I'm looking for powerhead... would you use 2× slw-10 or a scp-70 ????

 

[dank reefer]

If use the 2× slw-10.

I had a similar tank and had a CoralBox qp-9 and a qp 5 in it. qp 9 was over kill, but it did the job keeping the tank circulating.

I have 2x jebao slw10 on opposite ends of a 20L. I have them on constant mode on the second intensity setting and it's plenty of flow for a small mixed tank.
