@ebeuerle Hi Jo - any updates?

Thanks!

@Jo Makes sense! Thanks for the update.

Here's the codes off the bottles for LaMotte alkalinity and calcium hardness: Code 7038-G (alkalinity) and Code 7042-G and 7041-G(Calcium hardness - need both). 5ml test tube used: need 5 drops from each for Calcium hardness.

Let me know if you need anything else!

Thanks!

@Jo how's it looking? Any luck in looking into alkalinity or calcium hardness? I have been using the Lamotte chems for both of these so maybe we can reuse them assuming the LEDs do the right thing.

Any update would be great!

I have been working with Jo from IORodeo and here are her testing notes for pH:

Hi,
I am interested in helping to get additional tests available for the colorimeter. In particular, I am interested in pH(6-8), alkaliniity and calcium hardness). This will allow for me to move away from my ColorQ colorimeter to just using IORodeos and will provide most if not all the tests that aquaponics folks would need.

Thanks!
