Triton says I have Tin! How to remove it!

[ReefEco]

How high?

One potential issue with tin is there can be many chemical forms with different properties.

Hi Randy - it is 24.67 µg/l on the ATI test. Not as high as some other numbers on threads I've seen, but before I start adding acros, I'd like to get it down. No other high metals, so I don't think I have something rusting, and it doesn't seem to be coming from my RO, or RO storage bin, as the ATI RODI test shows zero Tin. It is a brand new system (about 7 months) and 600g of new PVC, so from what I've read it could be leaching from the new PVC pipes...

Hey Dr. Jim - just got a ATI ICP with elevated Tin, and been reading some threads. How did this test of Power Cleanse go? Seems like cuprisrob and metasorb are hit or miss, or are least inconclusive for removing Tin. Thanks!

Power Cleanse was the only material that I did a somewhat "controlled" experiment with. (i.e. measured the tin with ICP tests before and after the addition of the Power Cleanse). There was no significant improvement with this product.
All the other products I mentioned were not "controlled" experiments but they didn't seem to help either. I concluded that the only way to lower the tin is to find and eliminate the source and do a lot of water changes. Plastics, without a doubt, were the culprits for me, especially plastic tubing.

Struggling with same TIN contamination issue. I have read that frozen food (brine shrimp) does have TIN. Can anyone confirm. Trying to figure out the source of the pollutant. My tank is around 9 months old. Source RO water doesn't report TIN.
Planning couple of water changes. Any suggestions appreciated.

I've not heard that any food is a substantial contributor to problematic tin levels. What level do you observe?

 

[Dr. Jim]

I would consider plastics, especially vinyl tubing if you use it. That was the culprit for me.

Can I ask what’s wrong with your tank? Besides this test you got that shows it? What ill effects are you experiencing that leads you to believe there’s a problem??? I’m really blown away by how many people do these test and get results and go chasing stuff that was never a issue the last 30 years before these so called “TESTS” were available… I say “so called” because each one varies from company to company.. keep up with regular water changes and none of this should be of concern.. I mean even if you don’t change water it’s still done without these tests… curios…..

Have you ever dosed H2o2 (Hydrogen Peroxide) to your tank in the past or currently?

Jw - why did you ask about the H202?

Some types of hydrogen peroxide can use tin as a stabilizer. Its nearly impossible to tell if it does without testing it if it says it has a stabilizer in it.

+1 on the water changes. I had the same thing when my tank was new. After several water changes it was removed and has not returned.

Why it might be a good idea to run a new tank with RODI absent of salt and conduct several water changes until any residual tin or other contaminants produced by the glass or gravel is removed. ICP after several cycles can confirm and then add salt and live rock or any other items that would not have survived during the flush out cycle.

One could also run the tank absent of salt with DI resin for several days until the tin has been removed. The approach I'll be taking. Cheaper than constantly making new salt, going to waste more DI with WC and guaranteed post ICP that one is now running clean. Any new tin likely from faulty equipment or something else added.
