I just recently added a powerhead with a flow rate of 175gph. My tank is 37 gal
with 15# of LR
and 20# of LS
I plan it add maybe another 10# of LR
and in 6-12mo I would like to have some anemomies and other small fun stuff. I was thinking of adding another powerhead. would this be too much flow? I am not sure what the filters flow is, but it doesn't seem to be too much. being a small tank, my fish selections will be small species, no more than 4- 4" fish when full.
