I have two oce's in a Qt one developed brooklynella, Treated both with fresh water dips and formalin. The formalin was an in tank treatment. After treatment carbon was placed in filter. My question is does this reappear like ich or will the in tank formalin treatment prevent further outbreaks. They have been in QT just shy of 2 weeks. Glad I did a QT.
