I saw a post from Tom Barr recommending spraying a 50/50 mixture of excel and water directly on the algae affected plants while they are exposed during a water change. I haven't tried it yet, but am thinking about it for a 10 gal that is having a BBA outbreak. The Amazon swords, which are otherwise doing well, don't look so hot with the black fuzz encrusting the leaf edges. :( Ken --------------------------------- Be a better friend, newshound, and know-it-all with Yahoo!
