Hey all, having an issue with the Salinity probe on my Apex, it keeps giving me false readings. I've calibrated 3 times now this month and it will either read high or low within a week. Getting to be pretty frustrating considering the price of these "lab grade" probes. Support from BRS/Neptune is pretty much a waste of time since it takes about a week to get a reply. Seems like this is a pretty common issue too. Can anyone point me in the right direction?
