Flourite is a commercial substrate material used in the place of or along
with sand or gravel. This probably wouldn't effect anyone else on the
list, but being a geologist, I know that "flourite" is also a common and
often quite attractive mineral. I find it confusing that the manufacturer
would use a common mineral name for their product.

If that's two 30-watt flourescents, light shouldn't be your problem. If
it's two 15-watt flourescents, then you probably need more light. The
common rule of thumb is to provide 2 to 4 watts of flourescent light per
gallon, but you can get good growth with 1.5 watts/gallon if you have the
right plants and the right lights. A lot of us build our own fixtures to
get the necessary amount of light.

CO2 is generated by yeast fermenting sugar water. You can get a
not-very-interesting alcoholic beverage as a byproduct.
