ALGAE ID...what is it?
I have a 55 gal that has been set up for 2 years now and this is my first algae outbreak. It has been going on for about 2 months now. Every two weeks I go in and clip all the leaves that I can see that are infected but of course I don't get it all so it comes back with vigor. Can anyone tell me what this algae is and what is the best way to get rid of it?
