I've had my checker since it first came out and is easily one of the most used piece of reef gear I have. It's been great until recently I am unable to calibrate using the Hanna solution packets. It just sits forever and err's out. I've tried 6 packets and all fail to calibrate at all. The strange thing is that it will calibrate in normal saltwater. Has anyone had this issue and is there a fix ? Thanks
