I have a 27 watt full spectrum fluorescent bulb I was using for indoor plants in the winter, and thought I could get away using that rather than buying a special aquarium hood. My husband made the aquarium stand with wood leftover from various projects around the house. The clear plastic lid was made from leftovers from another project. (Do we see a trend here?)
