Yes It was awesome for several months until I added the PB tang and had the resulting Ich problems. If I remember correctly I did a waterchange and started adding garlic. I seem to remember thinking...HMMmm it seems "Marie's" coral doesnt like garlic, the pollyps have all closed up. coincidence?

Nope I dont feed them, I am not running a ULNS system at all. I feed 2x a day, flake/ pellet/ bbs/ homemade mix.
