i have a 55gal tank with an emporer 400 on it and a prizm skimmer i have 2 aquaclear 201 powerheads in the tank thinking of maybe a third.should i leave my powerheads on all the time or put them on the timer with the lights so the fish have some time to rest.i read that somewheres but also ive heard to leave the power heads on. the tank is fo maybe some live rock not sure yet
