i want to put together a 5.5g nano. i want glosso, dwarf sag, and watersprite in the tank. thats it. i will be making a hood myself. what's a good light level for this sized tank with these plants? im going to do DIY CO2 and ferts. i was pretty much going to build a hood and paint the inside white, then attach two normal screw-in fixtures and use a couple spiral compact flourecent bulbs. what wattage should i go for in such a small tank?
