I go sick of dosing and went out and got a calcium reactor. I purchased an SL2 and PH probe for the reactor. The problem that I a having is that when I go to calibrate with PH the packets the numbers do not move to calibrate it. What I need to know is, is the probe bad or is it the SL2. I looked all over the internet but could not find this problem anywhere. Any help would be greatly appreciated.
Thanks
Kevin
