Thanks for the compliments!
The other light is a 150W Metal Halide, and is a real hassle to turn on and off. It can't be on for too long either. My plants plants are all pretty new, and offer the algae little competition.
so I purposefully bought a low power light to use the rest of the day. It was cheap enough that I didn't mind cutting it up a little. It may have been around $20 (plus or minus 5). But get this... my fish look better under it than the MH. The MH is a 6700K coralife with a cheap electronic ballast. The T8 is a 'daylight' from GE that claims a temp of 6500K. The tank certainly isn't as bright, but every time I come into the room when the little light is on I notice that the black neon tetras have orange over their eyes, and the water is MUCH clearer looking.
I think maybe I went overboard on the lighting, but with a little ripple on the surface that MH sure does sparkle nicely... well, at least until you get a headache.
The blue light were way cheap too, I got 100 off eBay for $10-12. The resistors were about $5... a little expensive, and had I thought I'd ever use more, I could have gotten 100 for $12 (maybe 200, I forget).
