Any ideas on how to remove tin other than a couple water changes?

I really wouldn't worry about those levels, assuming that's µg/l- it could even be a false reading. I was at 100µg/l and snails and other inverts were fine short term. I found Cuprisorb helped a bit, but large percentage water changes are best.

The corals I have moved to a different system seem to be improving daily, I'll update with pics soon.

Did you find a resolution for this?

in my experience, it tends to be related to an imbalance of cal/alk, and also can be related to Boron deficencies though your ICP rules that uot.

here is a good thread:

Thanks for this, the link doesn’t work for me but I have read numerous threads from a number of boards. I know many pointed to a dosing imbalance (I try and dose very equal amounts of the big 3) but I also see a few reporting this problem using calcium reactors, which would normally result in equal mineral addition.

These are some (low quality!) night-time pics after moving two corals to a different system, for about 4 weeks. The polyp structure is definitely improved and the blistering is almost non existent

I've gone through bouts of this, though at this point it's mostly cleared up after ceasing carbon dosing months ago, brining nitrates and phosphates down, continuing my weekly water changes etc... I suspect it's bacterial as well, as I don't dose except for a calcium reactor and set amount of kalkwasser. I've recently gone through a months long cyano bloom which I finally killed off with chemiclean. Replacing the uv bulb and regular carbon changes have helped clean up the water. I've been cleaning up detritus from the small sand pits for the wrasse weekly for the past few months and nutrients seemed to have stabilized at their right lower levels, so I suspect any remaining extra carbon sources have been used up. Some varieties seem to take it harder than others, namely BC sky doppel, two Efflos and the sarmentosa, similar Granulosa and my single nasuta (sp?). The tenuis, torts, various smooth skins and for lack of better understanding "shortcake" like varieties never seemed to be affected. To me, the big corallite varieties seemed to be the most affected. I'm curious if others have noticed any similarities? It seems like if there is a flat surface for something to land on it affects them more than the more jagged ones.

I’m also seeing this on some of my corals (acropora). The coralites are very bumpy and a few get these blisters where the skin balloons out and detached from the skeleton. The blisters will go back down after a day or so. But the coralite structure isn’t returning to normal.

I’ve never done an ICP test but I do weekly 12% water changes with Tropic Marin Pro. Ca, Alk, Mg, N, P are always pretty dead on with N~3-5ppm and P~0.02-0.05 ppm. I have always theorized a bacterial infection and after watching several corals stall today I’m trying to dose antibiotic (Bactrim, I already have some on hand). I’m not sure if it will work or not but I have to try.

When I see this, I’ve noted my strontium and boron levels are undetectable, adding both seemed to have reversed the problem over time - may be worth an icp
