Mindstream Aquarium Monitoring System

I figured that was the case. That makes it just too expensive for my needs. I had really hoped the Thrive water testing station would work out but it looks like they just stole money from the LFS's that signed up for it. It would be nice to just take a water sample to the lfs and get accurate readings for things you don't need to test for on a regular basis or to test the accuracy of your current test kit.

I believe Triton is trying to do that with Triton Envoy.
 
There is a whole lot of different efforts going on to do in talk monitoring of parameters. Non are cheap but will be a game changer once they get to the consumer level. An will be very useful for those wanting to control processes in their tank. We all have to just set back and see what actually comes to market.

Are there any articles about what happened with the Thrive water testing station? A LFS near me was listed on their site probably two years ago, and I asked them about it and they were excited to be getting it "any day now". It still isn't there and they no longer sell any Thrive products.

According to my LFS, he ordered his at MACNA, I think it was 3 years ago but maybe it was 2. To be listed on their site I think you had to give them a couple thousand dollars and that meant you would get them when they came out. Same here, he no longer carries any thrive products and I don't know any LFS that carries them now in DFW area. Used to have 6 or 7 that did. Last time I talked to the owner he said he had written off the deal as a bad mistake. He didn't think he would ever get a unit now. Every time he contacted them they had a new excuse on why they had missed their shipping date. He said the last time he had talked to them they were having to redo the machines because of corrosion issues.

It's very relative to the topic of realtime alk monitoring and potential control. Something that is now a possibility and a direct reading not calculated from other parameters.

It is an automated Hanna Alk checker (or similar).
It is not a titration unit which is the only accurate way to test Alk.

What makes you think that it operates similar to the Hanna Alk checker and is not a titration? What I observed in the video, and how Jim described the process certainly sounds like a titration is occurring to me.

For that matter I would be extremely pleased with a Hanna like approach based on absorbance (what the Hanna uses as far as I can tell) over a titration.

The product was shown in MACNA. Simple as that.
It draws saltwater sample, then draw and reagent, test the color, then discard the waste.
 
Colorimetric alkalinity test is for estimate, it is not an EPA-accepted procedure.
But for this hobby, it may be OK a long as you know what to expect.
Using colorimetric Alk testing to control dosing pumps could potentially (just potentially) dangerous.
 
I am sure you have used the colorimetric tester and have found it to be dangerous.
Since it is still in testing and has not had be released to the public. No need for FUD.
 
Hmm, I disagree with your conclusions. Let me start by saying that I don't know Jim, but I have read many of his threads on MBI, and he is a smart guy (from what I can tell).

As for your concerns about using a dosing pump in this system, I would normally be right there with you, but the dosing head that Jim is using is a really nice Japanese dosing head. Most likely stepper based version. Not the usual Chinese crap that many aquarium manufacturers base their dosing units on. You can see the same dosing heads used in the expensive Vertex dosing units.

As to the reagent and why you think it is colormetric in nature, I highly doubt it. I would guess that the reagent is a dilute acid (either hydrochloric or sulfuric) combined with 2 different PH indicator dyes. If you notice the waste and reagent are different colours, signalling a colour change has occurred during the process. In one of the demonstration videos, Jim narrates the process that is occurring and it most definitely falls inline with what a titration sounds like (E.g incremental amounts of reagent are added to the sample until the end point is reached).

The system looks pretty much like what any of the test kit manufacturers use for alkalinity, only automated and with electronic output fed back through the PH port, with far more precision than the typical hobbyist is able to achieve using clunky test kits.

Right - it was supposed to be available for purchase now with delivery in early 2018. You can't order it now so I don't think they'll be delivered starting in early 2018. These guys don't provide any status update or reason for the delay which makes me wonder about the product....
