Please, call me Flame...you make me sound so formal!
I would personally take that black pad out. It's a carbon pad, and while it's made of a different material than the white floss pad, it can still cause algae problems.
Glad to hear you found the light! I'll be getting some soon enough for my 6 gallon Eclipse, so I'll be happy to hear how they work out for you.
My exact situation with the Azoo tank is a little bit different than yours...I was working at a LFS at the current time, and we had it sitting underneath a 400w metal halide pendant...so of course I was doing massive topoffs. As for the water changes, I took out about and replaced about 2 cups a week, which was fine for the Acro's we had growing in there. After I left the store, I took the tank with me, but not the MH pendant...it's sitting on my desktop now, empty, looking forlorn...
As a little extra tidbit of nonsense...I fashioned a tiny, DIY undergravel filter for the Azoo out of the top of an impeller box, as well as made a tiny gravel vac out of airline tubing and 1/4" ridgid tubing...we had a lot of time on our hands there
I mainly used it for the Acro's, although I also grew some caulerpa in there, so I could harvest the sprigs and give them away with Tangs people bought. The MH went a long way
