ive got this aglage in my 100 gallon fish only tank.
Its only on the sand
the tank has been setup for almost 2 years and no changes in a long time.

this algae only grown under the highly lighted sections and i can rake it but it comes back in a few days. Its been going on for many months now.

What eats it?
