Moss Balls/Marimo Balls (Cladophora aegagropila)
Anyone have any experience with these? I have always been intruiged by them, and I think it would go well in my 20 gallon tank. I think they look neat and from the research I have been doing, they "help" control algae by using up the same nutrients as the other kinds of algae that grows in tanks.
Thoughts - good, bad, etc?
