Reef One Algae cleaning cloths are an effective way of removing algae without scratching your aquarium.
Cleaning clotes are double sided with a smooth side for removing light algae and rougher side for any stubborn algae and even limescale build up.
They are non toxic and safe for fish and plants.
Reef One do not recommend using other algae pads on the Bio Orb or biUbe as these may scratch the acrylic and the cleaning pads should only be used on the inside of the aquarium.
