Selling my GHL controller. P4 was purchased in 2020, KH Director and Doser 2.1 SA was purchased in 2021. I bought the Maxi Doser used last year and never set it up. Everything works and turns as shown. Probes are original and you'll most likely want to replace them. The KH Director has a pH probe and also comes with an unopened pH probe. Also included with package is a mechanical level sensor for ATO use, probe holder, dosing tube holder and calibration reagents. Asking $800 for everything plus shipping.
