Really low light!
So I've got a 45g standard tank(about 36x24x12) and only the standard hood with a 20w(maybe HO) bulb in it. I threw 4 Amazon Swords in pots, filled with org. potting soil and topped with play sand, into the tank a couple weeks ago, and they are actually growing and looking alright. No CO2, but the light runs 12-14 hours a day, looking to cut that back though.
When I do get a new light, probably a shop light with good bulbs, and maybe overdriven, what should I be looking to get as far as wattage? 36" lights are more expensive and harder to come by, but I don't really want a 48" hanging over the ends of the tank...
