Same here, I had metal halides on my last tank. Now, I just like having a couple fish and corals. Less headache and less $$$. I have also sent an email to coral life, their suggestion will be the least amount of time to help sell their product. Like I said, everything is fine, no more brown crap, for now, corals are fine, except on head of my geren torch has retracted and turned a flourescent yellow? Oh well, its only a frag. Thanks!
