upgrading to a 40 gallon planted/lighting
 

I just bought a 40 gallon long seaclear aquarium. Upgrading from a 30 gallon unplanted. The lighting that came with it is a 24 inch t-8 20 watt bulb. It says 20 is the max wattage for this light. IT does not look like it will be nearly enough light. It is very dim. any suggestions would be greatly appreciated.

anyone have any info on what i can do

Thanks for the non responses. Really appreciate it. Your sight sucks.
