I feed floating Hikari WG and turn off the one skimmer in the feeding area with a remote control (Skylink brand, available from Target.com, approx. cost = $15) then turn it back on when done.
During the summer, when I have the FOK auto feeder going 5x per day, I have a digital timer (Intermatic brand -- programmable, outdoor) on that skimmer circuit which turns it off just before the feeder activates and then turns the skimmer back on 15 minutes later.
They're easy to use, inexpensive and best of all there's no food loss.
