Will we ever see an Alkalinity Probe?

[jimmcwibb]

Lab-on-a-chip style titrators are showing promise in academia. It would just take someone to turn it onto a consumer product. You'd still need a reagent, dye, and at least 2 pumps.

It's not a probe but it's way more likely than the mindstream thingy ever giving alkalinity.

Website says 2015...we'll see.

I'm hopeful but just don't see how its possibly going to work for alk. That said, I'm no chemist so who knows what they have up their sleeve.

All I know is that of it works, I'm buying it.

Testing for me is the single most horrifying thing about this hobby - I despise it.

Yeah i would spend 150-200 for a automatic tritrator that samples my water every few hours or daily and logs into neptune apex. Would be awesome for calcium, alk, mag

The answer may just in front of you, and not discovered for 8 years.

Look this Equilibrium PH calculator vs pCO2
http://www.hamzasreef.com/Contents/Calculators/EquilibriumPh.php

Everyone want to measure pCO2 in your tank, then from PH value, you get dKH.
However, there is no cheap technology to measure pCO2 in your tank. it is the bottleneck.

There is a stable pCO2 source just sourrond you, it is outdoor pCO2.
The pCO2 in your tank is not stable, and change from day to night.
pCO2 outdoor is relatively stable. Check this daily keeling curve. pCO2 variation is within 5 ppm. Monthly is the same, 5ppm.
https://scripps.ucsd.edu/programs/keelingcurve/

Use this stable outdoor pCO2, fully mix with a small bottle of tank water by air stone, wait equilibrium, then you get equilibrium PH value. Get dKH by test kits like salifer, and from this calculator, you get outdoor pCO2. Just monitor equilibrium PH, and you know dKH.

5ppm variation of pCO2 result only 0.005 PH change.
All you need is a two digit after decimal point, well calibrated (PH7 and PH10) PH meter.
dKH change from 7 to 8 result 0.05 PH change.
It is good enough as a dKH monitor.

I couldn't make it half way through that video with the host blabbering on like an idiot.

I feel like I am trespassing being in this forum since I am no chemist by any means, but that video seems like a good concept, minus that fact that I no longer can have a pH probe...

Marc is a really nice, albeit quirky guy. Chill brah.

Base apex has two pH ports. If you are using both you can add another module to add another probe. Biggest issue on this will be price. My understanding is that parts alone are close to a grand. If someone buys the intellectual property (I'm looking at you, Neptune) it will easily be 2-3 times the cost of parts.
