Re: [APD] Re: BGA Control - Blackout vs. Antiobiotics.

I think it is important to follow the exact directions on the box, to
prevent resistant strains from appearing. I don't know for sure, I am
not a scientist, but I suspect it would be possible to have a
resistant strain from appearing if:
1) you did not do a full cycle of medication
and/or
2) you did not change enough of the water after the medication period,
which would leave smaller amounts in the tank giving the BGA time to
grow resistant.

Of course, this is speculation. 

Fortunately, my live fish were unharmed by the treatment I used, but
all the plastic fish died. =-(

The most merciful thing in the world, I think, is the inability of the
human mind to correlate all its contents. We live on a placid island
of ignorance in the midst of black seas of infinity, and it was not
meant that we should voyage far. The sciences, each straining in its
own direction, have hitherto harmed us little; but some day the
piecing together of dissociated knowledge will open up such terrifying
vistas of reality and of our frightful position therein, that we shall
either go mad from the revelation or flee from the deadly light into
the peace and safety of a new dark age.
