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 ????
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.
