Thever,
I had a small problem with hair algae in my Riccia. I then picked up about a half dozen Amano shrimp. They have been going to town on my algae, both on the riccia and the java ferns. They really do a great job picking the algae off and leaving the plant intact. The little guys are always active, picking at this, or cleaning that. I think they make a great and interesting addition to the tank, and do an excellent job with algae cleanup.
FYI, I also have a few ghost shrimp, but they are not nearly as effective. They stick more to the gravel than the plants, in my short experience. Anyway, maybe something to try to at least assist in your algae cleanup. Just in a few days with them in the tank, I noticed a difference.
