Any chance the probe needs calibration? Not an expert on ORP but that seems rather high.I need more bioload lol.

Then it does seem you need more poopers in that systemI cleaned it and it dropped down to 425. I have a backup probe that was brand new. I tried it and its numbers were very similar, so it is not likely a calibration issue.
This is what I observed just yesterday when I brought my UV back online after a few months of discontinued use. I dose ozone for 10 minutes every hour. My ORP dropped from a measured 270 to 170 within 4 hours of turning on the UV. I'm now going to turn off the ozone and see what happens.I wonder if ORP meter might tell you about the OPOs presence or destruction. Seen people running Ozone talk about how their ORP dropped when they brought UV online due to the UV destroying the ozone that would otherwise stick around in the water longer.
I’ve read on R2R where hydrogen peroxide lowered ORP. Perhaps UV-C created hydroxyl radicals when contacting ozone create the same affect as hydrogen peroxide catalyzing when contacting organics. No clue. Just speculating as this is still relatively new info I’m still digesting and likely getting confused.This is what I observed just yesterday when I brought my UV back online after a few months of discontinued use.

Wasn’t referring to metals. Just the affect observed on ORP when ozone in combination with UV-C was utilized. Might be the same dynamics overall yet in detail quite different yet achieving the same results to certain goals such as eradicating pathogens/bacteria or removing certain toxins or issues present in our systems.I don’t think either hydroxyl radicals or ozone can reduce trace metals (copper for example) the way hydrogen peroxide can. I think they can only oxidize trace metals.
Thought I had read that you or another mentioning that the ORP drops because of the oxidation happening at an accelerated rate or something like that. My thinking on what might be happening when ozone is exposed to UV-C.The hydrogen peroxide effect on ORP is because it acts as a reducing agent in seawater. That’s why I mentioned it. Ozone with or without uv won’t act as a reducing agent.

Wasn't aware of that. Was considering using UV-C with ozone in QT to eliminate nitrification of ammonia since it converts it to Nitrate although not sure how it then converts nitrates to nitrite although not as concerned about that in salt. Was then going to perform periodic peroxide baths of 150 ppm with UV-C off then post treatment use the UV-C to dissipate the peroxide which would also further sterilize the water during QT. However, wanted to have the option to still use copper if needed and specifically Copper Power therefore does this mean I'd have to suspend peroxide during copper treatment as I thought you had previously stated that peroxide converts copper from one form to the other. So much to learn it seems just when something makes sense a curb ball thrown and more study needed.No,not me. Hydrogen peroxide is known to reduce copper in seawater, which would reduce ORP,
Why I'm going to run tests. Only one way to find out. Although still seeking knowledge before trying it out as it might affect what tests I run.I'd have to feel really confident I knew what was going on with the copper chemistry before I tried therapeutic levels of copper medications with varying mixes of Ozone, UV, and H2O2.
possibly oxidizing and/or reducing large amounts of copper in a system with livestock sounds really hard to predict.
I’m injecting ozone into my skimmer. Bringing the UV online simply means turning it on. It’s been plumbed to the system for years. I turned it off a few months ago.What does bringing it online involve? How are you using ozone?

Today, my ORP is 225 and climbing. Still lower than it was with ozone only but higher than with both ozone and UV. There must be some reaction that lowered it.
Interesting. Even though the probe is in a chamber upstream from the skimmer and uv? I have a total of 400 gals and the return pump runs at about 1500 gph. It takes a while for the uv treated water to reach the ORP probe.I am more inclined to think it impacted stuff on the probe than actually lowered ORP.

I can be sure but well less than an hourWell, that does make it less likely. How fast did the ORP drop? Minutes, or hours?
