Yup, thats black PVC pipe you can get in all sizes at a home imrpovement store! Scrub the labels off best you can with those metal wool scrubbies.
Actually, I hate that sand because everything shows on it, funky algae grows on it, and theres no way to get the funky algae off because you cant gravel vac sand very well. When I can, I'm going to convert back to gravel or do black sand. White sand looks nice the first couple months, but after awhile it just goes kaput LOL
But, I got the sand at Petland. Not sure what brand, however it came in 5lb bags. I'll probably get black from the same brand because it settled fast.
If you get really low-light plants, it's likely that they'll work out if you have flourescent lighting in your tank :)
Thanks for all the nice comments you guys! :D
