This is a subject you will see brought up countless times on every forum but here's my input.
1. There is no proof that spot feeding your coral will make them grow faster.

No I guess when a coral can use photosynthesis to remain alive that is would be hard to prove that feeding them will make them grow faster, however if they are eating then is should be safe to assume that this will aid in growth, if not why would they have the ability to consume food?
Nonetheless I use the following schedule. On night one I mix some coral frenzy and feed the whole tank. The corals with polys do extend to snag what they can. Since most corals eat in the oceans and their polyps are not just for decoration but to catch food, I leave my flow on. Besides my mandarins love it, they swim around with their mouths open to catch what they can. I try to feed close to lights out so some food is still circulating for my chalice (he still won't feed with lights on)The next night I add 20 ml of reef plus. Since I don't dose Styronium, on the third night I dose str. and at times will add a couple drops of logol's iodine. Then a night off, then I start with coral frenzy again. This is just my thing, but seems to be working.
