I have thought about using ozone for a long time, for some reason it freaks me out. I've read letting it escape into the tank is BAD and would be continuously worried it was escaping into the tank. I have a EuroReef RS-135 skimmer which says using ozone will hinder its performance (not likely) and is bad for the skimmer. I would love some basic ideas, thoughts, about how I could employ ozone in my 90 gallon tank. I seem to have a fairly high level of DOC's which has been a constant battle. I've had 100+ aiptasia (probably way more), hair algae, cyano, bubble algae, red turf algae...the list goes on. So if someone could give me some idiot proof ideas on how I could add ozone to my tank I would love to hear about it. Thanks. BTW I have read a lot about this, just confuses me. Thanks again.
