Nice tank! What kind of soil do you use in an aquarium? I always thought you had to use sand or a kind of fine gravel. That's pretty awesome it is completely self sufficient and you do not even have to use a filter! I don't doubt anyone's advice on the LEDs, but I think I'm going to see how it fares with the low light/low care plants I'm considering and based on that decide whether to purchase a more powerful light. The only one I have found is a 13w power compact but doesn't that seem a little much for a 2 gal tank?
