My tank has been up and running for a couple of months now and I have yet to grow any algae. My tank sits right across the room from a double window yet no growth at all. I know, most people would be happy with that, but it kind of worries me a bit. Besides, I like the look of a tank with a healthy algae population, as long as the sides are kept clean. My water isn't too hard, my pH is around 7.4 and the tank is a constant 76 degrees. Am I doing something wrong?
