I just got my first ICP test results and am concerned about the amount of Tin detected (32 ug/l). I was experiencing some RTN in a few acros (3 out of 14) and did a 50% water change before sending off the ICP so the original reading might have been around 60+. Since the water change, the tank has stabilized and I'm back to getting good growth, colors, and PE for my SPS. However, my zoas continue to melt (ongoing since I transferred everything over to the tank 4 months ago) and mushrooms still look mediocre. I'm not sure if Tin is causing any of these issues but it's the only number that really jumps out to me.
I know why my other parameter are out of whack (need to adjust trace element dosing and stop dosing N/P) but can't pinpoint the cause for Tin. No other heavy metals are elevated. I can't find anything rusted. This is an AIO so I don't have any PVC plumbing either.
At what level is tin toxic? Any recommendations on how to locate the source?
