Using travertine for substrate instead of none or sand.

Hey,
I was just looking at your pictures and a thought occured to me about the windows on the sides of the tank. How much sun do you get from them? I know that in the summer
(Okanagan) I get quite the build up of algae on my tank. I never close my blinds. But in the winter it goes away. Looks really great, are you putting fish in?
