i give up on these color changing tests!

[thedragon]

Being color impaired, it is next to impossible to get accurate test readings! Any user feedback on the Hanna alk and phos texts?

I have used the Hannah phos colorimiter and do not like it.
Nothing to do with its capability but the curvetts or vials have a very small opening
making it difficult to work with.
I prefer the Milwaukee Martini version, the vials are much easier to work with.
Can not speak on alk as I can distinguish colors.

use hanna for both alk and phos, love it. You are welcome to come over sometime if you want and try them out

the api alk kit has a dramatic change from yellow to purple, should be able to see that.

Hanna alk and phos work great. Easy to use. The calcium is a bit more difficult as preceise measurements are needed. I wouldn't use anything else.

Lol, welcome to my world. Fwiw, I use both the Alk and phos checkers from Hanna. That said, I found the Salifert Alk test not too difficult to read. The complaint about the Hanna phos is that it's kind of a pita. That is true, but if you are careful, it's really not a big deal.
