Aquarium Advice Regular
OK, this one has me baffled...and concerned. I have a 46g planted tank that has been established for about 2 months. Yesterday I finally started feeling good about the looks of this tank, and thought I could stop examining it like a lunatic all day long. Then tonight I noticed a huge number of these tiny little green "dots" on the glass. It's algae of some sort, but nothing like I've ever seen before. They are all no bigger than the size of a pin-head which wouldn't be a big deal except I can barely scratch these things off with my fingernail by reaching down into the tank! There are hundreds of them - which would take me hours to scratch them all off. The sponge does absolutely nothing to them.
WHAT THE HECK KIND OF ALGAE IS THIS? What might have caused it? And better yet, any suggestions how I might stop it from spreading? This could be a disaster if this propogates.
