The green algae that lightly covers the entire surface of driftwood and black beard algae tends to grow on a bare surface of driftwood. For this type of algae, Siamese Flying Fox (Crossocheilus siamensis) and Parotocinclus maculicauda are effective. If algae growth is significant, you can drain the water from your aquarium and apply Phyton-Git with a brush directly on the driftwood exposed to air."
