A lot of guys don't realize that a PH or ORP probe degrades when it no longer can be calibrated correctly which you should get a minimum of 2 years out of standard probe. Oxygen and salinity probes are solid state and last indefinitely as long as they are maintained properly. A quick search on Reef central will give you this info on at least a dozen different posts by people who are certified in this area. Thanks for your post though.
