Amy,.. That's why I suggested the soil for you, as it breaks down it let's off CO2 to some degree

- Plus your habbit of overstocking works great for CO2 additions in that tank
My most recently setup FW tank uses 1 6500K bulb, and one 10K bulb - Before that I always simply used 5500K - 6700K bulbs.
Really depending on the tank size you would probably be better off to just go get a cheap shoplight from HD using NOF bulbs. (shrug) it's what I did with my lower light planted tanks.
