What is the best Alkalinity test kit? Right now I am using Fastest. I doesn't seem very accurate to me. The instructions say to add the testing solution one drop at a time until the water turns a greenish yellow. I could add the entire bottle and never see a green hint to the water, it's always just pale yellow. Is this right? It's the same color after 4 drops as it is after 10.

Is there a more accurate (digital) way of testing?

I think Salifert is the best for Alk

I use the salifert one and have not had issues with it.

I have used both salifert and seachem, I think both are fairly accurate but seachem is way faster than salifert. Salifert has a very good reputation though.

Elos is the only brand that's certified by a Lab Standards association (Jason can probably elaborate more on this since I don't have the papers in front of me).

How precise is the Elos Alk test.I have the Mg test,but it only tests in 100's.So if my test says 1300 it could be anywhere from the mid 1200's to the mid 1300's.Easy test tho.
