I don't think flourescents are bad. They just seem to be responsible
for more rapid algae growth. I prefer flourescents, but will sacrifice
them to limit the algae growth.

- Do your tanks get any sunlight? Are you over feeding? What does the
- algae look like?

No direct sunlight. I don't think I'm overfeeding. The algae is green,
attached to the glass, mostly, and sort of growing out from there.
