Tin levels

[mkpetersen]

Sorry. I know this has been discussed before, but I'm having trouble sifting through all the posts in the forum to get a clear answer. Recent ICP shows my aquarium is at 16.86 µg/l of tin. Is this a problem, and how might I correct it if so? I'm currently running 3%/day auto water changes. Thanks.

That may not be high enough to be a clear problem, but there are loads of different tin chemical forms that will have different toxicity.

Tin can be hard to track down the source since it can be plastics of many sorts.
