Well there's a few different options.
You could go with the Black Tahitian Moon Sand from Petsmart, although 20 pounds is still going to run you about 20 bucks (<---lol I almost wrote buckets XD) BUT! It's going to be a lot easier to clean than if you got Black Diamond Blasting sand which would just need a super, super clean. So the Black Diamond you can get at a Track Supply store in 50 pound bags and I think it's only like 15 bucks or something.
You generally want 2 pounds per gallon, so if you did the 10, you'd use the whole 20. But if you're like me, I like to make hills and stuff to make it more interesting so I use a bit more.
So you've got some pro's and con's
Con: A little more expensive
Pro: Easier to clean
Black Diamond or something similar:
Con: harder to clean
EDIT: incandescent lighting is...okay. What you want to look for is something with a Kelvin around 6,500k, that's what natural sunlight is at. But you can use bulbs anywhere from 3,000k (If I'm remembering that correctly) to 8,000K and it will grow your plants. But the closer to natural sunlight the better. Also you want to look for something that will penetrate through the water, LED's and Fluorescent's are good at that. But that's more for higher lighting plants, if it doesn't reach the bottom much, high light plants will die.
