I have used it years ago when I first started in SW but have not since. I did use it due to ICK but treated fish with garlic and selcon and no reoccurrences. NO I dont QT my fish for 3-6 weeks I do dip them and my coral and watch them for 24 hours then toss them in. I am a very firm believer in no matter what the tank it will have ICK. I dont have anything going on just looking at ideas. But I just wondering if others have used this or do use it regularly, When I did use it I noticed my green corals were much more vibrate and the hippo had much deeper blue along with "some" corals having more polyp extension. Yet it always shut down the skimmer it would go from foam to nothing like a can of "soda" head that was just touched with oily hands.
Any thoughts on this are very welcome.
