Once it's on the surface treating it is a waste of effort IMHO as it grows on the bottom and floats to the surface. I would physically remove the floating FA and if you still fill the need to treat the bottom growing FA use Cutrine Plus granular.
However I defer to more knowledgeable folks here.
Anybody?
So is this FA a continuous growing plant/algae? Or does it just come and go? Will it go away on its own?
