ORP high with and without ozone

[servus]

Added a 200mg Ozotech generator to a Milwakee MC510 controller with ORP probe, about 5 weeks ago.

Here's the timeline:
- week 1: start ORP 200, generator setting 2 (out of 10), running with the skimmer 10h/day, controller set for 300
- week 2: ORP went up to 300
- week 3: ORP went up to 400 (ozone generator not triggered)
- week 4: ORP went up to 450 (ozone generator not triggered)
- week 5: ORP stays around 450 (ozone generator not triggered)

I am concerned at this point, read the other threads, will soak the probe in vinegar and see where it gets me.

Take 2 cups of water: one with bleach and one with tank water.

Swirl the probe in the bleach for a few seconds, then swirl it in the tank water.

In a few days you should get normal ORP readings.

Set up controller for slightly 450, ozone generator started, three hours later ORP at 430. Did not dip the probe yet.
