Alk test!

The tester on right I have been using…both new batteries. So what now???

PH is 8.3

Same reagent bottle? Alk can vary with test kits, consistency is what matters. Hanna does make standard calibration vials that you can use. https://www.saltwateraquarium.com/h...ZodRsFZspujj3JOtDwdA8vlv5jWj3DakaAnVMEALw_wcB

What's the Salifert test kit below on the shelf say? I'd trust that over the Hanna

I have them and they were supposed to test between 90 -110ppm and my tester tested 80 with hanna testing vials

Since the checkers have a +/=.3 tolerance. They are still with range of each other. As long as they are consistent.

I get it, but it’s annoying

Make sure your glass vials are spotless in the area the light goes through. Super clean.

Are you getting all the powder in? Measuring solution exactly the same for each?

Sensor inside clean?

I realize this ain't your first rodeo but it can be amazing how we can make the most obvious mistake to someone who would watch us with an analytical testing lab mind.

The Hanna Checker can not be calibrated, those are just to check the checker's acuracy but there is nothing you can do to change it.

I made sure everything was done exactly a like…I’ll wait for the regent files…double check again and see what happens.
