I didn't actually read past page 3 so not sure if this has been mentioned but...
I've been maintaining a 6.8wpg "propagation chamber" for a little over 4 years. Lights are on 12 hours/day no matter what. The only time it grows algae is when I get lax on the ferts for more than a week or 2, and even then the algae only grows on the very bottom of the glass, hahaha like as far away from the light as it can get. You can actually see a line where the algae will not grow, as though it was cleaned all the way around the perimeter to 1/2 inch of the bottom or so. But as soon as I get back to dosing the algae goes away completely and it turns once again into the only tank that grows no algae!

Just a thought...
