Hello all, just received my new APEX/Neptune A3 Pro set up since my other unit decided to leave it's electronic world and just die. Along came the ORP probe and a slight crack in the vial of fluid that it was shipped with. I hooked it up and tossed it in the sump, because for all that I can research, ORP is just a ratio and 650+ is a nuke to the tank. I know it's not something that should be monitored like other aspects of our underwater worlds, like PH, ALK, Nitrate, Phosphate, ect. I have little belief that the ORP probe is in range as it wasn't fully submerged and most of the liquid was not in the shipping vial, and looking up how to calibrate it, the consensus is get a new one, don't try and calibrate it.
Welp, as of right now, I am not running ozone, and really not moved to order a new probe just to have; so, help me out.
1. How many of you have an ORP probe and watch/observe it to the point you would be willing to replace it?
2. Do any of you run ozone WITHOUT an ORP probe?
3. Is there something else you'd get/watch over replacing ORP probe? (Currently watching: ALK, CA, MAG, Temp, and PH. Weekly test: ALK, Nitrate, Phosphate, CA, MAG, Salinity, temp.)
