I have to turn all pumps off and spot feed mine. Otherwise stuff just gets blown around and they barely catch any. Waste of food.
I wake up for work at 4:30am when its dark and all polyps are out. I feed each coral. Let em eat while I take a shower and get ready for work. Right before I leave, I turn everything back on. If you feed something with large polyps you can see them eat. They even poop later in the day. Just like lps/anemones.
I feed my sps 1-2 times per week. Some are difficult to feed due to really small polyps. You just gotta hope they catch some. If not, no big deal, feeding isnt manditory having good lights. I would highly recommend it though. It isnt hard or time consuming at all.
