Redox potential isn't even measured in ppm, so you're measuring it wrong. It's an electrical potential, not a concentration. And the impact on fish health is pretty unclear in this context, ie, extreme ORPs are harmful, but will our ORP ever reach this level with reasonable maintenance. WCs are most likely far and away superior to UV for maintaining ORP, as pointed out in the article.
Yes your right it's not ppm it's mv
This is a screen shot of a stats read out of the readings on my tank no ozone just a very high dose of uv
I think 420mv is good don't you
