I love my Coralife 30" 1X65W 6500K :lol: I am running it currently over a newly set up 20-gal long, which has the same depth as a standard 10-gal; just longer. It fits ok; the bulb is positioned to shine the middle-center, leaving each side about 2-3" with less light. Still works really nicely, though.

Very good point in mentioning the need to add CO2 with higher lighting. I am also running a 65W on a 20-gal long and this is the first week. I am lighting it for just 8 hours. It's a nice experiment to see if that will indeed minimize algal outbreak because in the past I've always had some sort of algae problems with tanks that I light up for 10-12 hours even in their initial set up.
