I used to never feed my corals,,, until I did,,,and now that I do,, I will never not feed them again ,, I am feeding Fauna Marin LPS pellet food to Acans, Bowerbanki, Scolys. and polyps. Colors and growth on my corals are wayyyy better now than when I wasn't feeding. I am using the bigger pellets for the larger corals like Scolys & the Bowerbanki, smaller pellets for the Acans and Polys. I turn all my pumps and power heads off when I feed

I am not sure if I am over doing it or not,, I am feeding pretty much every 3 to 4 days, no algae problems so far, I do have a good clean up crew and a Bi Colored Fox Face in the tank though.
I will say this though, you can't feed one time and then say,,, I really never noticed any difference,,, If you feed your corals Fauna Marin pellets ( I am sure other foods on the market are just as good,, its just what I am using ) you feed your corals for three months at least once a week,,, at the end of that 3 months,, you will never go back to not feeding your corals.
