Checking alkalinity

[taylor8528]

What's the best way to check alkalinity?

With a test kit. Salifert an Red Sea are good hobby grade kits.

API kits are notoriously inaccurate.

I like my electronic hanna tester for alkalinity. You put water in a vial, seal it and put it on the little machine. Press a button., Take out the vial, add the reagants and put it back in the machine and press the button. Ta da it displays an exact number for the alkalinity. easy and quick. They cost about 50 bucks but they are notoriously ACCURATE. lol

I agree, love my Hanna testers.

Check Amazon, I would avoid EBay as you don't know how old it is, and most reagents have expiration dates

Just got my Hanna tester last night and it read 172 which is 9.62.

My API said 12, the LFS's API said 6.

You think Amazon cares how old they are? That guy he linked has 18,000 feedback. It's perfectly safe buying from him.
