Should I turn powerhead off at night?

Water currents in nature dont stop at night.













Or do they?
 
my powerhead is timed to go on w/ my co2 only.
i want it to go off at night so my fish have an ease at bed time.
besided the filter is circulating water, so ther is current.
 
if you are running Co2, i'd recommend turning your power head on during the night when the lights are off, and off when the lights are on.
 
Best answer so far. LOL. No they do not stop.

but they do indeed change.

On another note, you could also feed the McDonald's to your fish and then become the first person to sue McDonald's for making your fish obese or blame their death on it. If it works for fat kids, why not fat fish?
