Question for folks using CFL Spiral Bulbs
I see a lot of folks using the CFL bulbs with a clamp light. My question is what wattage of bulb would you use for a 10 gallon low light set up and how many (1 or 2)? I'm not running CO2 and don't want to, so recommendation on a wattage and bulb type would be helpful. I do have some cover plants that will block a little light.
