should I get an ozonizer?

I thought dryers were used to take out any moisture in the air before it gets to the ozone generator.

At any rate you should do a quick search here on the board as I recall there being a nice thread about the pros and cons of ozone.

I use a small 50mg/hr Sanders unit injected into my beckett skimmer's air intake. I run very low doses as I use it only to polish the water and take out the yellow tinge to it. If you wanted to start using ozone to control your ORP, then I would suggest a unit with a controller (though I've read somewhere that those probes need to be replaced often).
