Hello, Today I was shopping in home depot. I picked up 2 bulbs for my 20g long tank and came across the GE f20T12/aq/ws bulbs. Was wondering if this was a good bulb and is there any recomendations on better bulbs? As of now I can see a marketably difference in my tank, there seems to be more light penetration (oh, btw was using coralife trichromatic bulbs, never again) Ed
