I'm setting up an aquarium for the first time, on a very tight budget (college student). Lighting is too expensive. Is there anything that could be used to filter sunlight to mimic the natural water filter many feet below the ocean's surface? I know it would take some mirrors, a huge window, and a lot of luck to get the light into the aquarium 12 hours a day. I live in central Florida. We get tons of sunlight. I know this sounds crazy, but I was just wondering.
