Battles with Algae

I kept the fish tank in the dark from June 18-24 and the algae seems to have abated a little in my 55 gallon. (Luckily there are no plants in there!) Since then, I have switched the light timer to an eight hour on cycle, so that the tank is now lit from 1:00PM - 9:00PM. There's definitely still algae in the tank, but it seems to be a little less rampant anyway. We'll see how it goes.
