Did you have any problem calibrating you PH probe on your ReefKeeper? I have the ReefKeep lite, went through the calibration process like they instruct. But after I went back to the main screen, it reported the ph was 8.7 and I still had it in the 10.0 ph packet. I'm pretty sure that I saved the calibration properly after doing the cal using the 7.0ph, then the 10.0ph packets.Wow. Thanks for your input Windy.
I use Hannah checkers for alkalinity and phosphate. Salifert for calcium and magnesium. My reefkeeper does pH and salinity.
