ATI ICP Results Help

[Feiwen]

Starting having issues with some chalices receding and decided to get an ICP test since I was unable to narrow it down. Does anything stick out that would cause this. Iodine and Manganese are both low. Tin is showing a little elevated along with Phos. I've since got my Phos to .07. Any suggestions?

It looks like you're only really lacking iodine. What do you supplement your tank and corals with? Trace elements, coral foods, etc.?

Too be honest, that looks pretty good. There’s a few elements elevated a little and iodine is almost depleted, but other than that it doesn’t look too bad. I would have left the PO4 where it was because it was in a nice ratio with NO3.

Your salinity is low, and all the "ideal value" are calculated based on the salinity

A lot of us come back at 32-33 on ATI and believe it may be inaccurate. I’ve calibrated several pieces of equipment and they all read very close to each other (+/- .001) but the ATI constantly says 33 when most of mine say 35.

Curious…

There are two ATI ICP results at the top of the chem forum and both claim 1.16 ug/L copper.

Coincidence? Systematic error?

I’m guessing an error. We’ve had a few come back like that lately. I sent one to Triton and then had some really crazy results too.
