Is it normal to get spotty and very stubborn green algae on the aquarium glass? It only seems to form on the front pane which is curved. The tank is far out of direct sunlight, and doesn't get any other algae at all really. Any suggestions?
Yes, its totally natrual to get green spot algae on your glas, its actually a sign of a healthy tank.
To get rid of it?
Start scrubbing, thats the only way friend.
