newbie question

DT, Marine Snow. Stuff like that. But I would say most of the coral food comes from you fish poo.
I use DT sometimes. but not on a regular bases. My 25 fish in the tank feed the corals good enough.
Just my opinion

 

I'd like to add on - How often do you feed your softies?

 

I feed mine 3 times a week. if this helps

 

I agree with the fish poop thing. I do have a candy cane coral, which is a LPS by the way, that I picked up a couple weeks ago and it was in pretty rough shape. I've been nursing it back to health by feeding it plenty of light and spot feeding it cyclops when the lights are out and it has it's polyps extended.
