    Standard Low KH readings

    Hello,
    Would like some help troubleshooting my KH director. I calibrated the KH Director pH probe last week and now my readings are anywhere from 5.3 to 6.9 (test kits results are 7.7-8.1 dKH). Prior to the calibration, the KHD was working fine and was consistent with my test kits (Salifert and Hanna). I have recalibrated the probe two more times and calibrated my doser pumps and still no luck getting the readings. I have no bubbles in any of my lines. Any help is appreciated.

    Vinny,
    Did some troubleshooting on my own and reading thru some posts here. There are three things that I did:
    1. Change my sample water volume to include the tubing going to the KHD.
    2. Moved my KHD reagent bottle closer to the KHD supply line. Was close to the max recommended distance.
    3. Recalibrated my KHD reagent doser
    Results: Over the weekend, I have been consistently getting results closer to my test kits. Hopefully, it continues to work!
