Yes, thanks for posting the info.
When you made it, did you notice any solid precipitate on the bottom? That's not uncommon for IO, and might account for alk and calcium to be on the low side.
No significant precipitate. I mixed a small batch in a 5 gallon bucket for this test sample. I didn't see anything at the bottom when I emptied it. Calcium was low, but Alk was over 9, which I don't consider on the low side, at least not for a salt like IO that's not intended to boost parameters like Reef Crystals.

We do test for total ammonium routinely (on our cation IC). However the ammonium value is not part of the regular report. however, we do warn the customer if levels are elevated.Thanks!
I wish they would have tested for ammonia.
IME, alk is usually higher then that in normal IO, but it may just reflect batch to batch variation or inhomogeneity in a bucket.
Potassium seems a lot lower than I’d like.

How do they code the batch numbers on retail packages? I looked at a RC-50 bag that I have and could read some numbers:
unreadable text : 3222 18809 : 2
Seems like the batch number for mine is 18809?
Thanks,

Anecdotally, and my tests would not be anywhere as accurate or precise, but my IO alk always comes in around 10-11 dkh and the Calcium always hovers between 415-430.Yes, thanks for posting the info.

My Hanna HI-755 checker gave me a result of 9.86 dKh. It was consistently about 0.5 dKh higher than Oceamo ICP-MS for the four tests I had done (one for the new salt batch, one for each of my three reef systems).
Agreed. I add KCl to my two part to keep my levels around 400-410 ppm. I view salt mix as a starting point. Even if a salt mix is very close to NSW you're still going to have to dose to match consumption of certain elements, so I don't see a few things being low as an issue. Perhaps consistency is more important. I buy a pallet of salt at a time, which lasts me about a year, so I'm hoping the salt is consistent throughout the batch.
I've always been curious about trace elements and their impact on corals, but have always been skeptical of dosing anything that can't be measured. I'm pretty excited about the ICP-MS testing Oceamo is providing. I plan to start dosing trace elements in a manner aligned pretty closely with the Reef Moonshiners program. I think ICP-MS enables one to do this in a controlled manner.
Have you sent out an ICP-MS on your system to compare? What's your water change regime?
I'm in the process of adding a few things that show up on standard ICP. I'm already dosing K to the mixing water to boost. Mg, Zinc and Iron are next in line as they are showing up on fresh mix IO but not in my system. Most of the rest are zero, so I'm intrigued by the MS readings you have gotten.
