Hanna checker cuvettes

I posted this on the Hanna page, but have no responses.

I have 3 Hanna checkers that I use to monitor 2 tanks. I also ordered 4 additional cuvettes and caps. How important is it that the cuvettes are used with only one checker? If I clean them thoroughly, can I use the extra cuvettes for both Alkalinity and for Phosphorous?

Thank you!

In theory, if you could clean them well enough, interchanging would be okay, but I'd keep the cuvettes separate. I don't know what the reagents are for the kits, so I'm not sure what it'd take to make sure the cuvettes are clean.

The purpose of the zero procedure prior to each test is to get a good baseline. Spas long as you don't get fingerprints on it between the zero and actuall test that's the important part.

fYI. I talked at length with the Hannah rep at MACNA who informed me that despite several claims, adds, websites, and slick sheets, the Hannah Nitrate meter is for freshwater ONLY!!! I plan on getting a refund.
