Brown Algae

Brown or diatom algae appear as a brown, slimy film on aquarium surfaces. They typically occur in new tanks or when nutrient imbalances emerge. Brown algae consume silicates and are not harmful to fish, but they can be unsightly.

Red or brush algae have a red or black appearance and resemble hair-like growths on aquarium surfaces. Brush algae are notoriously difficult to remove and can be stubborn nuisances in the aquatic environment.
