Desinfecting the tank this way is rather useless as with the new fish
and plants you will have a great chance to reintroduce the
Mycobacterium. Just optimize the water conditions and don=92t make any
large changes (most of all temperature), that will keep you fish
healthy.

Betreff: [RML] Mycobacteria/Disinfecting Tanks
=20
Thanks Peter for the link. It had some useful tidbits.
There was lots of talk about disinfecting tanks, gravel, etc with=20
chlorox, ethanol, and other chemicals.
However, all Mycobacteria are quite heat sensitive. One scientific=20
study (Appl. Envir. Microbiol. Vol. 58: pp 1869-1873. 1992. "Heat=20
Susceptibility of Aquatic Mycobacteria") shows that 90% of M. marinum=20
are killed within 1 min at 60C. M. fortuitum, which is more heat-
resistant, takes 4 minutes at 60C.=20
Since Mycobacteria don't produce spores, you can easily kill them=20
with hot water (akin to "milk pasteurization" to kill the=20
Mycobacteria that cause human tuberculosis).
So I sterilize filter material with very hot water.
I would like to update my article in a month or two with more=20
information and scientific references. The egg sterilization thingy=20
needs some more investigation. :-)
