Triton results with high tin
 

Has anyone successfully been able lowering tin levels? I read through Randy's poll about pvc and tin but there wasn't a strong conclusion. Wondering if there is something else besides metal clamps and pvc that could cause it???

I don't know of any way to lower tin levels other than water changes, although I'd be cautious about interpreting data from Triton on trace elements. Their methodology might not produce accurate results:

I ran a magnet through my crushed coral bed and found some wire bristles from a stainless steel brush I used awhile back to get rid of some algae. Maybe it is from that lol could it be that simple.....

Interesting enough I just got back a result from Triton with high Tin. Which just about a month ago Triton registered 0

Some people are saying new pvc piping. Did you add any?

Not anytime recently.

I just received my triton test results back and My tank is testing at 2.11ug/l of tin. My lithium levels are way high also. My sps corals have not been happy of late. Poor growth, decrease in p/e and have been experiencing some stn and occasional rtn. Several of our local club members have been experimenting with almost 100% water changes every 3 months or so. So far they have been having very good results.

How high is way high Li levels. I've seen many great tanks with levels near 1000. I don't know what impacts it has but it seems extremely minimal and not enough to worry.

Tin you want to make sure you don't have metals in or around your tank. Even a piece of metal out of the tank can slowly drip moisture or flake off into the tank. Or some like the above posts have suggested pvc as a source. If so its another one I wouldn't worry to much about at those levels you stated if it's even accurate.

My lithium tested out at 392 with tritons recommended set point at 200. I guess maybe that isnt too bad. I cant think of any metals that might be leaching into the water and I dont have much pcv in the plumbing, what is there has been in use for years.

That Lithium level is fairly common.

I had freshly mixed Instant Ocean tested and LI came back as 368ugl/l

To re-affirm Jason. It's pretty common for salt mixed to have LI levels like that so it's most likely from your salt and not much you can nor should you do about it. Extremely unlikely to be your coral issues.

I can't speak to the Tin issues. I have never seen a detectable level of tin from my tests nor have I researched toxicity levels of tin.

I agree that our salt products seem to be fairly high in lithium. I'm not sure what ingredient in them is the problem, although I assume that it's a contaminant of some major ingredient. That might not be true, though.

So how do I get rid of the tin that is in the system's water? I am assuming water changes?

It's hard to know exactly how accurate that number is with out more data points

If the measurement is real, which might not be true, then water changes would reduce the level unless the salt mix itself is the source of the tin.

Great article! Thanks.

You're welcome.

I used the hot tub/spa version of Metasorb, and it worked for me.

MetaSorb probably would help. I should have suggested a PolyFilter, although I'm not sure that they remove tin. I think that if the source is removed, water changes or even just time should remove the tin. It should precipitate over time.
