With network connectivity? Cause I was gonna say the Reefkeeper Lite can do ORP. But the RKL doesn't support the network module. So until they release the new PC application later in the year, you'd be limited to reviewing the data on the head unit. And the RKE w/ NET ain't happenin' for under $300.I just wish there was something in the $200 to $300 price range that would monitor and datalog pH, temp, and ORP on 1H intervals. I guess I am going to have to go with an AC3 or Apex system to do this though.
