Newtankgirl:
I'm the one who wrote the BGA chemotherapy piece. You can squirt the H2O2
directly into the gravel. You want to get the peroxide in contact with the
BGA. Peroxide is a very powerful oxidizing agent. It does very similar
things as bleach (but without the chlorine, obviously). The point of using
a dropper, as others have noted too, is to get the peroxide into intimate
contact with the BGA in a fairly undiluted state. It's not difficult, and
as long as you don't use too much, you really can't screw up.

My advice is to go slowly and treat a little at a time (say a few square
inches (*6.25-ish square centimeters).

This sounds like a better way to go with the BGA in my tank than using
erythromycin - I only have small patches of it at the moment. I just
did a small test patch and it's bubbling nicely. Weirdly, several of my
cories seem to be trying to eat it

In my tank, quite a bit of the BGA is at the front between the
substrate and the glass, which I gather is quite a common site for BGA.
Do I just poke the dropper right down into the gravel to get to it, or
are you only supposed to use the peroxide on the surface of the gravel?
