I have a 46-gallon Seaclear bowfront aquarium. The stock hood it came with only allows two fluorescent lights. I have live plants and need to increase the lighting to at least 3 bulbs. Where can I find an alternative hood? I would be fine with one that was not designed specifically for my aquarium. Since it is acrylic, and part of the top is covered, I think any fixture that sits on top of the aquarium would be fine. Any suggestions?
