Set up a "odds and ends" 20 long. Got peat and mulm in the bottom. Topped with 3" profile, onyx and flourite (onyx from another tank and flourite from a tear down) Had a single 24" tube VHO set up with an aquasun bulb from the tear down as well. Retro fit it into the full hood and there ya go! This is gonna be fun! I am gonna use just a power head to move the water and havent decided on a heater or not. I figure the "75 watt" VHO wont be too much since it is a) in a full hood and b) not using a decent reflector at all. A lot of wasted light but its what was on hand + I really like the color of the aquasun bulbs. Makes the fish and plants look great
