RE: Lighting
I see this reference to a minimum of 3-4 watts per gallon all of the time
on all of the lists (Discus-l, Aquarium, and Stripes) and I think it is a
crock. Lumens are much more important than wattage, not to mention type of
plants, and depth of tank. I prefer Ultra Tri Lux because they are
extremely bright and my plants grow very well with them at 1.5 watts per
gallon in a 20L aquarium. It is 2 15w 18" bulbs with the bulbs overlapping
in the middle of the tank. Quality of light and lumen output of bulbs
should be a much higher concern than wattage. The bulbs that came with the
strip lights were only about half as bright as the Ultra Tri Lux bulbs,
thus I would have to of had 3 watts per gallon if I were going to use
crappy bulbs. The other things I credit my plant growth to is the use of
Kent's Micro Nutrient Supplement and use of a DIY CO2 source if the plant
growth stalls.
