I bought one these 24watt T-5 to be my second bulb in a two 24watt fixture. After looking over the fine print on the box I notice it is just for Marine use. Will it be any good with plants at all. The second tube is a 24watt 6700. It is on a 29 gallon 30" tank. Really is bright, but big on the blue spectrum. I was looking for a 10,000, but they were all out.
