I float crude oil on the surface of the tank and light it. It makes a nice
amount of light and lasts a long time.

Hi all,

I'm very much into environmentally friendly alternatives. And a
seriously considering putting together somesort of solar assisseted
lighting system for my tank.

Just wondering if anyone else has other green ideas or tips for fish
tanks.
