How many powerheads?

[AMYZINGnano]

I've got a Fluval 13.5 mixed reef. I just upgraded my pump to the loop current usa eflux 660 and I'm thinking about adding another one. Would two powerheads be overkill for this nano tank? Also I'd like to see what placement you all are using on penisula tanks like this.

If they are DC controllable, not a problem

Yeah... as said above... better to go up one bit to the 1050 gph and dial it back on the controller... nice to have a little extra capability stashed.

I have a return pump and an MP10 in a 5.5 gal display... I certainly wouldn’t judge. For me it is the right amount of flow, but I don’t crank the MP10 up either
