You're very welcome, Coleman.
I sent Tom Barr this newer reference solution how to. I believe that it is OK to post what he said to me: "Thanks, now go forth and post everywhere that have hobbyists that use garbage test kits that sorely need calibration!
I'm amazed that folks will pay 250$$ for a 17 gallon ADA tank, then say they test all the time with a 8 dollar NO3 test kit claiming they do not need a Lamotte nor calibrate the cheapo test kit.
I gave up trying to get folks convinced to test right.
So I figured EI would resolve a lot of that, water changes are easier for most to do/rationalize and understand.
Thanks,
Tom Barr"
Then I sent this response to Tom Barr: "It's on TPT right now because ColeMan mentioned making reference solutions."
