In both of my tanks, I got very dense, fibrous, stiff, hair-like algae everywhere a few months after adding the marimo balls. In the discus tank, it spread low among the dwarf saggitaria and attached firmly to the Flourite substrate. In the smaller tank, it wound itself throughout the valisneria. Once I figured out that the marimo balls were made of the same stuff, I took them out of the 2 tanks. The Amano shrimp have eaten it all in the small tank. It is still in the discus tank but not spreading that much.
must my $0.02. If you like marimo balls, put them in bare bottomed tanks.
