I have a few frags right now, but some seem to have turned a bit brown from when I got them originally.
My caps and montipora have lots of color though.
My water is good almost no NO 3 lots of light 250w DE on 25gallon.
I am a heavy feeder though I believe in feeding my fish daily.

I also have some clams so don't want to starve those and I have lots of sand in my system so zeo-vit might not like that.
I am wondering if I should go to the Zeo-vit system.
Anyone have a deep sand bed and is running the Zeo-vit?
