Have an Apex I have had for about three months. I’m dosing two part and my salinity was raising so I needed the full.

Have an Apex I have had for about three months. Just don’t really need it to only monitor temperature and PH so I bought a full version. $400 shipped . Or trade for a trident plus cash. Don’t know why anyone would do that since they would seem to be getting out. But it’s worth a try.
Is this for the complete system also are the probes well kept? Please advise
