Ozone in tank? Ozonizers? Your thought!

[Quinster]

There was a thread a while back where people opened their controlled ozone generators and found the controls weren’t even hooked to anything.

I don’t remember the brand or what forum I saw it, but with control like that, and for the price of an ORP controller, I think it is an inexpensive piece of mind, especially when using such a potentially dangerous item as ozone.
