Another invasive that people love to put in their aquarium (and subsequently dump into a pond where it grows unchecked
) is parrot feather, which I'm sure you're familiar with.

The blue-green algae are indeed bacteria. they are now considered cyanobacteria the cyanobacteria that fix nitrogen in (Azolla) is a microscopic filamentous blue-green alga or cyanobacterium (Anabaena azollae).

It also looks good used as a ground cover in bonsia trees. As long as it is kept damp it will grow as ground cover and it looks like a real scaled down moss or ferns in bonsia pots.

Got any pics?

I also use it to purify the water in my aquariums i set up with out filters. I harvest the Azolla every few days off top of the water and it keeps the nutrient levels down.

I wonder which is more effective at cleaning the water, Azolla or charcoal?
