	What I am told is that the CF's will burn out before they drop below 90%
original light output, and about 3 years is what I am told is the average
life expectincy of a bulb.  Since the tank is 30" deep you just need to
remember that the strength of the light is getting weaker with every inch of
water that it travels through so if you use more lighting 3-4Watts/gallon
there is a better chance of getting more good light to low growing plants
and other things near the bottom of the tank. Just my thoughts but I think
that's all you wanted.

	Rob I don't know for sure but I don't think you will get the best CO2
diffusion by running the hose into your filter box. You might be losing to
much through the surface of the water.  As for the charcoal you would
probally be best to cut open the filter bag empty out the charcoal and the
use rubber bands or something else to hold the material to the frame when
you put it back into the tank.  The activated charcoal is a very cheap
quality and contains more phosphates then you want to mess with(if I
remember right it's something like that).  Good Luck
