Uggghghhh I've had a bit of a blue green algae problem in my 10 gallon tank. It began when my tank started getting direct sunlight in the afternoons. It got under control enough for my snails to eat it when I stopped turning on the tank lights... but then my plants were dying because it wasn't getting direct sunlight for long enough. Anyway, i started turning on the tank lights again, but the BGA came back. it wasn't too noticeable until I switched from dark gravel to white sand... within a few days the sand was coated with BGA! ewwwww. My snails don't eat it off of the sand :roll:. So I tried to vacuum it up tonight, but it's too heavy to get sucked up all the way. It comes off in nasty sheets. So I vacuumed it and dropped the algae in piles and I had to scoop it out with a net. It's really bad. How do I get rid of it?!
