Hi All, My tanks is slowly starting to build up Algae on the side of the tank (the glass). Although it isn’t very pleasant to look at and obstructs my view is it actually a problem? I have a small group of cherry and Japonica shrimps who seem happy to scale the walls feeding on the Algae but it makes no real difference to the amount of Algae on the glass. If having the Algae there is benifitial for the shrimp and won’t cause any problems to my water or tetras then I really don’t mind to much. I don’t want to clean it off if this is the case. Any advice would be much appreciated.
