I use this for almost ever res mix. They are good for starts and semi pros. Get all the right bottles to make sure the cal is good.

In my opinion Hanna is a fine company however recently there has been an influx of returns on their pens. It is commonly a user error however these are the same users who are using Bluelab and not ever bringing them back. I was using a Bluelab about three times a day on 9 nute tanks and when the calibration reminder check mark ( great feature) went away, to my surprise the meter was only .o1 off. If it were me I would spend the extra money on the Bleulab. You will save yourself a headache and possibly a few trips to the hydro store .
