great info, i have chaeto growing in my main tank and in my overflow w/o light, but it also grows faster in my sump with a 32watt cf light, my hd has cf flood lights w/reflectors built in, they work great, i have it anywhere between 4-6 inches away from the water, i lit it 12/12 and 24 hours, i didnt see much of a difference in growth or in the tank, i think as long as its still green and slowly growing its working. one thing i did notice was i have (i think0 more pods/critters with the 12/12 lighting, i think because the light was off when i looked into the sump
