I'm new to planted tanks and I'm grateful I found this COOP. The videos have been priceless.
My questions is, will I need more than one light for my tank. I'm sticking with low light plants and I have a Fluval 3.0. The tank is fairly deep. With substrate it will range between 22" and 18" deep. I don't plan on running Co2. The full dimension are 30"x19"x24". Someone recommended two lights at that depth.
Thanks in advance.
