i have read that running ozone deterioate your seals. ie orings or any rubber seals in your tank. Have anyone experience this before while running ozone?

Ozone is brutal on most rubber. In fact, way way back in the day, they measured ozone concentration by how deep it cracked rubber for a given exposure. Some rubber is more resiliant than others. I wouldn't be surprised if it is ozone which causes old car tires to crack (ozone from "pollution chemistry")

..but ozone does react with water (slowly) and may be fast enough not to be a significant issue.
 
I've had no problems with running ozone all though some of the tanks we'd have to change the ball vale seals yearly. The thing is though they opened 30 - 80 times a day as they were electric ball valves (computer controlled) on massive surge tanks. I doubt any ozone got to them. The closest area to where the ozone treated water housed all the probes and such. IIRC they had rubber housings around them as part of the mount we made. It never had a problem so I assume they ozone was depleted enough by then to not be an issue.

It is nasty stuff though and something I wouldn't run on my home system since it's in my bedroom :p

i hope i am not derailing this thread but what's a decent ozone system to start with?

i looked online and there are tons of models ranging $50-$500.

$50 sound good to me :)
 
I have an Ozotech 150.

As I understand, there are two ways to generate ozone, corona discharge and UV. The corona systems like the Ozotech tend to be pricier and can generate more ozone than the UV ones. I think the UV ones work fine though. To be honest, I am not sure which one is really better, but I got a good deal on mine used...

All that said the Ozotech unit is built like a tank and has been hassle free for years.
