Just got Hanna Alk checker. Got a reading of 134ppm. What does that mean. All I know if range is 125-200 means 7-11. Where's chart to read these numbers. I don't understand why there's no chart to compare these numbers.
Not surprising with your results, hence why I sold all my Hannah kits
I use red sea pro salt and red sea text kits end of story it is what it is.
If you test a fresh batch of Red Sea salt with their test kits it will be dead on.
