How many desk lamps would I need to get med to high light? I have to get 6500 cfl bulbs correct? And do I have to worry about golden mystery snails if I didn't use a hood.

You only really need two lamps (could get 15 watt bulbs or so). You would get better spread if you got three lamps with like 10 watt bulbs, or if you got two bulbs that were a little bit stronger (around 20 watts) and raised them a couple inches above your tank to get better spread.

The nice thing about CFL is you have a lot of options, and if you don't think you have enough light or if you have too much you can just go buy different bulb sizes.
