I'm under attack by BG algae and have noticed that since the attack, there
has been no green algae in the tank. Before the BG attack, there were
acouple of bouts of green water, which were easy enough to cure by doing 90
percent water changes. The BG is resisting all efforts to control it, short
of chemicals which haven't been tried yet. I was thinking of brewing up
some real green water in a bucket in the back yard and dumping it in the
tank in the hopes that it would nuke the BG algae.
