It's a beautiful tank and set up. Maybe you can answer a question, as I am a relative novice aquarist. I've got a wicked algae problem that I can't solve. I'm certain that the issue is too much direct light, but my house has a good number of windows and skylights. Short of keeping the tank in the closet, I'm stumped. I've tried chemicals, sucker fish, cleaning every two weeks ... nothing stays on top of it. Any thoughts?
