Hi Shamsoo,

What are you using the Formalin to treat for? Generally it is not recommended as a preventative treatment without a proper diagnosis of some sort, but I would be very careful about it (ie Formalin = last resort in my book)

Was the tank newly set up or did it have other inhabitants before these 2? is it planted? Gravel? Is the foramlin milky or white? (ie formalin is no good if not clear)

I would just do a thorough scrubbing of everything...
