hello I did use it years ago, its an oxidazier, for proper use you will need a controller and to be specific you need an ORP controller
this way you dont run the risk of overdosing it,
I was running the tubing in the skimmer inlet instead to have a bubbler in the sump,
I was running it on a digital timer 1 minute 6 times a day, untill the timer got stuck on ON'
and lost few corals, UV sterilizer work in the similar way but if you leave it on it wont kill fish or corals just anything that passes through
the UV light from protozoans, algea, copepods, etc,
hope this helps
