Return Pump On or Off During Feeding

[input80]

Hi, I'm not too sure how to start a poll.
How many of you turn off your returns when feeding your tanks? The main reason I am asking is that I turn ours off for almost an hour (I know, too long), when feeding the tanks, rather than waste food to the sump. I have also noticed that our skimmers take a long time to fill up,running a Euro Reef 135 on the 120 gal & a BM Nac6 on the 80 gal. Is it better to leave the return on when feeding? We are not running socks.
