Ok for a while I've had blue-green algae growing in my tank. It spreads over the substrate in the front of the tank and climbs up the sides and some grow on my plants. Sob! I've tried cleaning and manually removing it but it kept growing back then I bought some erythromycin antibiotic to kill it but that just seemed to slow the growth down. So I kind of gave up getting rid of it. I just try to get rid of as much as I can during my water changes.

But today most of it was all gone! The sides of the tank and the ground are nearly clean! My hungry guppies ATE the cyanobacteria! Hahaha! Yay! I love guppies!
