I am running three lights in my display tank, and I am unable to get my plants to stop growing. I don't know the name brands, but one is a growlight, one is a blue spectrum, and one is the stock light it came with. I only use the blue to highlight my discus' colors. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
