Sould I use Ozone Generator Poisedon 200 or it's danger to my house?

Hello everyone, I'm very confused with this..my ORP stays around 250-300. My sump is in the basement and is no much air circulation., even I use air pipes 1/8 coming from outiside in the intake of my 2 skimmers. I was wondering if anyone has the experience with that. and how you bring air in Massachusetts in the winter without freeze the house. Thanks

ORP has nothing to do with air. Thats PH which is effected by CO2.

ORP can crudely be described as the fight between good stuff and bad stuff. Generally higher meaning better.
250-300 is fine, so long as it's stable. Big spikes means either something is likely dead or similar, or when you water change or dose stuff, including feeding.

So many things can effect ORP.

I found that when I had dino's and cyano, my ORP was very low, ~200.
Since it's cleared up, over a couple of months, it's now around 350+, and I do not run any Ozone, but I do run UV (not sure if this makes any difference to ORP, but I guess so).

There seems to be a relationship between PH and ORP, in that they typically ramp up/ramp down in opposite patterns. ORP down during the day, PH up during the day. (at least this is what should happen).
Or perhaps, it's just that you're feeding during the day means the ORP drops.
