ok thanks guys. So I've been trying to re-trace my steps... two weeks ago, I increased the lighting on the tank by 10% ( everything looked fine that week) the week after, I added the chemipure elite (some of the zoas didnt seem to like it) Since adding it the following day the water looked a bit clowdy (keep in mind I rinsed it like no tomorrow) I added a fine filter pad to the sump to try and clear up the free floating carbon. I've had to change the pad twice because this batch of chemi pure wont stop throwing out fine carbon. I also noticed 3 days ago, that there was a bit of a diatom bloom..I scraped it off the glass and didnt think much of it, and today I found my cosmic broc frag all shriveled up. After closer inspection, a lot of my zoas dont look as happy as before, a lot of them are kinda shriveled. I'm guessing I either stripped the phosphates waaay too fast, or I got a bad batch of chemi-pure
