Is this garlic ok?

I'm with Emily, Garlic Extreme works fantastic. Just don't drop the bottle on the floor (hard to get rid of that smell).

Danny, I'm not sure that the garlic you used would have killed your lionfish however garlic is one of those things that goes rancid really quickly. Storing it even in RO water may have caused a bacteria bloom of some sort, not off the RO water but the Garlic may have had a bacteria or a fungi etc. Prepared suppliments and medications are probably the best way to go, home made foods are always good but anything with oils can give you issues unless it's kept frozen until you are ready to use it.

Just my two cents worth.
