light ?

[iwantareef16]

is 2-40 watt bulbs enough light on a 55 gal to grow most plants. I also have the option to add to 2-65 watt pc and take out one no bulb

Not even close.

You need closer to 4-6 wpg to grow most anything except low light plants with much success.

There are a lot of low to moderate light plants that would go with your current equipment. If you add more lighting you should seriously consider a pressurized CO2 system as it is pretty much a necessity when you get above 3 wpg. Click on the link below and you can search for plants based on their light requirements as well as other factors such as difficulty, placement and region.

for 'most' plants, you'll want 4x55watt power compacts...in fact that lighting should grow anything. But 80 watts over a 55, doesn't even put you at medium light.
