Can anyone give me a good website to learn about lighting a tank effectively? I would like to populate my tank with low light plants so I don't need anything major, but I have no clue where to start, what I am looking for, or reasonable prices. My hood currently has one stock bulb, and I don't plan on upgrading from one anytime soon. But can I replace the bulb with something more productive? My understanding is that brown algae forms from lack of appropriate lighting, and my tank is just starting to show signs of this. I am going on a trip this weekend to pick up some driftwood, it will take me about a week to sterilize it and probably some time soaking to get it to sink, after I have everything set up I am ready to start planting before I add any more fish. Any information you may have would be great. Thx again
