Anubias can easily take up to four minutes.  Thin-stemmed, delicate plants
should only get two minutes.  It is very important to immediately put the
treated plant in a well-established---that means algae under control---well
lit tank with chelated iron in the water and CO2 additions.  Of course, you
should put the treated plant in a tank free of hair algae.  Otherwise, it
will be back on the plant in no time.
