congrats, a little TLC and elbow grease and you've got yourself another toy...er tank.
I've an 80 gal 48 X 18 X 22, this size is great for scaping!cheap lighting (not diy): http://www.fishneedit.com/t5ho-4ft--4lamp-aquarium-light.html or 2 of these http://www.fishneedit.com/150w-metal-halide-pendant-lig.html
I have heard that people like them and I ordered on myself last week.
You can now customize the light and have all white bulbs.I've an 80 gal 48 X 18 X 22, this size is great for scaping!
The lights from this site are pretty good, I have a T5H0 54W x 4 over mine and it works good. Just know that the bulbs (at least on mine) were 2 white and 2 actinic, so 2 had to be replaced. Also I had one ballast (each bulb runs on it's own ballast) burnt out and the replacement wouldn't fit so now it runs from under the tank. Even with a replacement ballast and 2 bulbs being replaced these are still a good deal.
Edit: Congrats on the great find!!
