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.

You could do without. You can have it running during the night and off in the day or you can run it with timer say every 2 hours. You still need a redox meter to find out what level you are at.

I guess, A ORP controller wouldnt be a bad idea since I have so much money in that tank. It would definitely give me piece of mind. Where could I get an ORP controller? and How much do they go for?

If you wait for a bit the odd one pops up for sale on the board. You will also need an air drier and a reactor chamber

Doesn't the red sea ozonizer, have the air dryer built in? Do I need those pieces as well or can i skip those cause my sump area isn't that big and I still need to fit another reactor in there.

Drier is attached to the ozone unit. You can feed your ozone through your skimmer but you should run carbon to destroy the escaping ozone. Mind you 50mg/hr is small. I have a 300 and 100 mg/hr units
