If used properly, it's a good investment.
Not only does it kill parasites and bacteria, it also increases the effeciency of your skimmer.
It sounds to good to be true, why doesn't everyone have one?Now you may ask...what's the catch?
The catch is, you need an orp Monitor/Controller. because you can have TOO MUCH OZONE in your tank and start killing fish.
ORP Monitor will measure the ORP (oxidation-reduction potential, or REDOX) of your system. It is popular with those who use ozone gas or potassium permanganate as an artificial oxidation agent in fresh or saltwater. Constant monitoring of the ORP is useful in keeping tabs on the overall health of a system, as a drop in ORP often precedes visual or other indications of trouble. Many serious marine enthusiasts who do not use ozone gas use this meter to judge the overall health of their reef systems.
So when the ORP level gets to a certain point it shuts down the ozone generator.
Like I said..if used properly, it's great.
