Extremely High Mercury & Tin Levels... Possible Culprit?

[sgrosenb]

Add me to the list of High Mercury Test results. This is my 1st time using the test so I don’t have a baseline. I also purchased the test kit from a LFS.

@reefRoss what do you feed? any unique points about your system? any other high metals? th I now for your info

I feed a combo of LRS and jumbo Mysis shrimp once a day. My aluminum/lithium is also high but I only have marinepure balls.

I'm not sure how the source of purchase makes a difference? it's just a vial. I'm still thinking it might be the frozen food?

More so just to get someone with more pull to ask if there was an error in their testing.

Also, I'm not sure how the frozen food could be it when my test levels are just as high but I am only feeding frozen once every could weeks.

Hi all - just got this message from Triton. Looks like there was in fact an error on the mercury:

"It has come to our attention that there was an error in your recent analysis.


The affected element was Mercury. The error has caused a false high reading. We are currently re-analysing the sample and will upload the correct report shortly. Please note that none of the other elements from the report were affected by this error.


We are sorry for the inconvenience this may have caused."

Thanks for digging in and getting the result we expected.

I tend to cut Triton some slack (1980s expression) because we are talking about very low levels that are close to the equipment detection limits. I think we need to look at the results more as trends than single point accurate results.

And this is why I haven't jumped on the ICP bandwagon yet.

Speaking from past experience on ICP, paying $500+ per sample to labs that are NIST traceable / certified still produces incorrect results on occasion. These instruments are very capable but require an enormous amount of training to use and can be very sensitive to problems with calibration... and I am sure running saltwater is particularly hard on them.

I wouldn't trust these kind of results unless they were presented alongside a copy of a calibration run done on a seawater standard on the same test date.
