feeding is a sensitive area. you have to be carful here or your water quality will deteriate quickly. I am a heavy feeder, but, I have also a bunch of filtration and equipment to off set the bad effects of feeding. I use, cube krill, mysis shrimp, brine shrimp, cyclopes, rotifers, kent marine three step liquid, and kent marines pyto, and photo plankton. corals are fed every other day at least and are fed at night at least 2 times a week, I also use cyclopes eez powder, squid, and have used small chunks of ocean shrimp soaked in selcon etc. so, I do not have a regiment of which food is fed only what I want to feed and change foods ofter to give all a variety. oh and I also use seaweed select. I do not target feed but it can be done. you just need to put a little in the system to get the corals to open or extend feeding tentacles then you target feed um. too much work, but, effective if you are concerned on water quality. hope something here helps. Corals only need to be fed 3 times a week if your water changes are done properly and your lighting is adequate for the corals you keep. good luck.
