Feeding Corals

[Madreefer]

Ok. So another question.
Is there anyone who has fed their corals and stopped? If so did you notice a change in specifically SPS?
I took my filter socks out last feb and I noticed better growth and color. Maybe coincidence I dunno. But it is another source of food (detritus). I'm seriously thinking on feeding Coral Frenzy twice a week for 6 months just to see if there's a change. But yet I don't want to pollute my tank. Thoughts?
