So I found an old 5 gal hexagon buried in the closet and thought I'd put it to use. For lighting I'm going to use a 16 watt cf spotlight mounted in a pendant type desk lamp.I use something similar in a fuge for saltwater with good plant growth,though plants grow more on surface. I am a little unsure about light level. they tell you 16 watts same as 60. So any opinions or plant suggestions would be greatly appreciated.
