Max ORP?

[TastesLikeChicken]

I started ozone yesterday. Increasing the ORP very slowly through a reactor. What do you recommend I set the max ORP at on the Milwaukee? I’ve read anywhere from 375 mV to 450 mV. Thank you.

I run mine at 400. It comes on when it drops to 380. 380-420 is my range. I ran that through a mutiny reactor. I run the same through a second skimmer now.

ORP is not a goal, but a safety preventative, IMO.

I’d look to have the ozone raise the ORP by some reasonable amount (say, 20 mV) compared to without it.
