Help Really High Tin Levels in my RO/DI Water

Much of my tank was wiped out a couple weeks ago. After much sleuthing I sent my water to Triton Labs and the only thing that was wrong with my RO/DI water was extremely high tin levels (see MR post https://www.manhattanreefs.com/forum...45#post1857045).

How do I get this out of my RO/DI water?

Does anybody have a suggestion? Is there an RO/DI resin that will remove the excess tin? Is there a water conditioner that will neutralize it? Kordon says their NovAqua Plus should, but I’m wondering if anyone has experience with it or some other product that is proven to remove tin that I can use in The RO/DI water before mixing in the salt.

I don’t store it. I make it fresh each time. The water tested went directly from the RO/DI unit into the test tube.

I know the source of the problem, but I’m trying to figure out how to either get rid of the tin at the RO level or neutralize it before the water is even mixed with salt. This doesn’t seem to be a common problem and I can’t find any info online specifically about dealing with tin getting through an RO/DI unit.

You live in Manhattan, so if the issue was with your water, everyone in NYC would have that problem. Tin is a component in solder so maybe you're picking it up from your building's pipes. Check the levels from a neighbor's apartment and someone else in Manhattan to see if the problem is isolated to just your apartment. Good luck.

Have you tried Cuprisorb?


See some of the recommendations here:

It's definitely the building. The building is new (opened in 2017) so tin leaching from solder is the most logical culprit.

Cuprisorb should work. Long term you probably have to continue using Cuprisorb or buy your RO/DI water from a LFS or a friend who will provide you with RO/DI water every week or 2 weeks.
