I didn't hear Melev say anything about comparison to ICP testing results. Has anyone done that yet?
Not really what I intended to imply. I would actually be pretty surprised if the Mindstream didn't work as advertised. As a matter of fact it does a lot of cool stuff that the Trident doesn't. But I have three tanks all controlled by Apex units. Each with DOS units and it greatly simplifies my life.

My opinion and impression is that the MM would be the benchmark, not ICP. ICP as used by the hobby has quite a few issues as outlined in @Thales and Dr. Chris Maupin’s excellent article in Skeptical Reefkeeping.

I hope I clarified my statement. If not, there appears to be absolutely nothing wrong with a Mindstream all things being equal. I own a business that requires a solid 80 hours a week and welcome reliable automation for my tanks. The Apex coupled with a Trident and DOS pumps does that for me. I still manually test a couple of times a week but nothing like I used to. I may even consider purchasing a Mindstream or two as a way to "at a glance" insure the continued accuracy of the Tridents on two of my tanks.

I have been thinking a lot about comparing testing devices. It's a crazy thing because they all have their margins of error and ratios and scales. I am looking for trending and using my animals as the calibration - when I think everything looks good, I test with the different tests and see where they fall and use that number for each device rather than an number from another device. I want them to trend in parallel, and if that happens, I can use any of them.
What is the "MM"? Mindstream?My opinion and impression is that the MM would be the benchmark, not ICP. ICP as used by the hobby has quite a few issues as outlined in @Thales and Dr. Chris Maupin’s excellent article in Skeptical Reefkeeping.

Thanks! I don't know what the benchmark is. See my response above. Sorry I didn't post it here!

Yes, this exactly!

I agree. I didn’t make my point very well, I was just trying to say that ICP testing as done by hobby oriented labs isn’t a superlative standard by which all other seawater testing should be judged. My guess would be that @JimWelsh and @MindStream folks have built devices that are excellent and are not inferior to ICP, not to mention that ICP inherently cannot measure alkalinity. To be clear, I am not putting down ICP testing, I think it can be useful.

Yes, Mindstream Monitor.

Do you mean Mindstream as a broader hobby wide benchmark? I certainly would not suggest a Trident in that context. The trident is at times off by as much as a few percentage points against its own calibration fluid. I suspect microbubbles. And thats another good thing about the Mindstream - no fiddling around with intake tube placement or worrying about the reservoir filling up.

There is no 'international atomic time' for saltwater tests. There is no device that is the 'benchmark'. I think this is the thing we have to stop searching for and instead, understand the limits and ranges of our tests, and report results in ranges.
The shorthand for saying 'My salinity is 34' gives a flase impression because you never really know what your salinity actually is just that the device you tested it on gave you that number. That doesn't take into account the +/-. Even with the Misco I use there is +/-1 so I really should say that my salinity is between 33 and 35. Same for other parameters.

I was not clear, as I mentioned above. What I was trying to say is that ICP testing is not a superlative standard by which others can be judged, it’s just as likely that the Trident and MM are at least as good or better. Nobody knows because we haven’t fully characterized their performance yet. My guess is that ICP, MM, and Trident are really good with Ca and Mg. I also suspect that MM and ICP are good at K. What I really care about is whether they correlate with what we are seeing with regards to the animals.

@Centerline As usual, you can trust Rich to give a more poignant and insightful answer than me. I have the same thoughts but my thinking and writing are not clear or as straight the the heart of the matter like Rich’s.

What I find surprising is that though most of the companies tout the 'precision' of their devices - they do not mention the 'accuracy' of their devices Some give the impression that because the precision is .05 - that that means alkalinity is measured accurately to .05 (or pick another chemical). Point being the accuracy of the Mindstream is better than hanna, saldiert, etc - We dont know about trident (at least I couldn't find any data on alkalinity accuracy (on the main page - it states accuracy and precision to (I believe .05 dkH) - but in the more detailed section - accuracy is not mentioned - and precision is stated to be .05 dKh.

Those trying to purchase I would strongly urge you to send them an email and say look, couldn't attend, tried the code, and it is expired. See what they will do. Typically most people will honor the code + or - a couple days.
Doesn't hurt to ask.

Sounds like maybe he should queue this up as a future podcast
And if he and his better half drink wine I may have to leave a bottle for him the next time I visit the aquarium.
