I've never tried one, although recently i've been thinking about it. I belive what I have is a bacterial bloom that just wont seem to go away.
I've cut down feeding to every other day, did a few good gravel vacs/PWC
, and still has the same amount of cloudiness it had when I began trying to treat it.
So has anyone ever tried one of these products? If so, which product did you use and did it work?
I'm still not exactly sure if I want to add anything (I'm weary of adding any chemicals to my tank), so thats why I'd like your opinions, then I need to decide if I want to try a chemical or put the tank into a "black-out" situation (Don't know much about it, but I heard it can work)
