Ok, so I'll stay in.

What I was talking about is cure, not prevention.  Hopefully my earlier

Your question was over the "best" way to treat BGA.  I wouldn't tell you
-- and I don't know of anyone else who would -- that at least some of the
chemical treatments your talking about don't work.  Whether or not they're
the "best" way to treat it is another question entirely.

So let's compare.  The best possible outcome with any of those treatments
is that the bga goes away and your tank is back in the condition it was in
to start with.  There are some complicated down sides that we don't need
to get into.

If you do it my way (which admittedly doesn't come with any formulas,
equations or kits) then your *worst* possible outcome is that your tank
returns to the condition it was in to start with.  Normally when the bga
is gone you have a healthier, more robust and more attractive aquarium
than you had to start with.  I think that's "best".
