Oh, right... about what could be salvaged. The only thing I have saved is my heaters.... but those were from the betta tanks that I was fairly sure weren't infected with TB and were glass.

From the TB tank, I tossed everything, and the bettas that died that I KNEW had TB, I tossed all their stuff too.... if it's a general death, I nuke, alcohol and keep... no decorations, no gravel, no plants, no filters though... ever.
