Can any one please help me
I just buy AC III PRO and hookup to my system every thing runing fine but few little concern
frist my orp meter will chase with my PH meter ( when PH high then orp high anh when PH drop low then ORP low )
second the ORP from ACIII PRO read 264 but red sea ozonizer read 442
is this any wrong with my ACIII or with my ORP reading from my ozonizer )

There is a setting in the ORP setup that turns on/off pH compensation. Make sure that it is OFF. Also, it takes a few days to a week to get good readings from a new ORP probe.

There is a break-in period for ORP probes. They typically start out reading low and go up 25 to 50 mV per day until they stabilize. It may take as long as 1 week to break in.
