Who Gives A Fish Forums

I'm at a loss here. My corals seem to be dying off one by one and I have no idea what's going on. I'll share a pic of my candycane coral - it was thriving just last week. Now it looks like some kind of growth is taking over. I've already lost a small torch coral, and another one has lost a head. The only change I've made recently is adding kalk to boost calcium levels, which were running low. Any advice would be a huge help.

I've had issues with LPS corals when Alk levels fluctuate wildly, even if it's a gradual change. Brown jelly's a possibility here, I'd recommend an iodine dip to start. I've dealt with it before and it can get ugly fast.

I'm worried about the spread - is there a way to contain this in the tank? From what I've read, it's either remove the coral or quarantine and treat. How can I prevent it from infecting any new additions?

Thanks for sharing your experience. I was thinking brown jelly too. Can you walk me through how you got rid of it? I'm curious about the iodine dip - do I mix it with water or use it straight from the bottle? Also, is it something I can find at a local reef store or would I need to check a pharmacy?

I got rid of anything that was looking rough and expendable, then I treated the rest with a reef dip - Seachem's the one I used, but I'm sure any iodine-based dip would do the trick.

To be honest, I've wondered if it's possible to whip up a homemade iodine dip, but I never got around to looking into it.

I'm not sure what exactly did the trick, or if I just got lucky, but I'm pretty sure being proactive is key to beating this stuff.

I'm still trying to figure out what triggered this whole thing - anyone have any ideas on what starts brown jelly growth?
