Hanna calcium accurate?

[gmerek2]

For those of you that occasionally check the Hanna calcium readout with test kits.... find that Hanna calcium reader is fairly accurate? Fast or is it just as easy to do a test kit?

I had one back with the old 150. I preferred the Salifert kits.

+1 for salifert.

I tried Hanna thinking the process would be easier, it wasn’t.

Ok. I’ll save my money

Hanna Ca only works with distilled water not RO. I didn’t read the instructions and was getting bad numbers so I sold it!  I spoke w the Hanna reps at MACNA, they claim it is very accurate (when used correctly)

PIA or easier than test kits

I like mine but refills are expensive.
