My turnover is about 4.5x per hour and my return is split into two 7" dia. filter socks (the output of the two skimmers share one as well). My turnover seems to keep the cheato happy and the socks take care of the bubbles.
I throw the 3 filters into the washer once a week and change them out with a fresh set.
