Well I'm thinking about adding Ozone to the aquairum. I wanted to ask those of you that have used them, what brands you liked over the others and pros and cons you liked with it. I'm also looking for the queitest unit as well. I plan on buying a reqular ozone unit, no bells and whistles and control it with my Apex. Not sure that is the best idea, but that is what is on the table for now.
