Yeah, I plan on getting some rock hopefully this weekend, there is a local rock shop, that has, lace rock, limestone, lava, limestone, just trying to figure out what I want to do, and to clean my sand, I took a 10 gallon bucket, but about half of the sand in there and filled it with water, turned my jet sprayer on, and let it jet through the sand, when I first started it looked liek chocolate milk, but after about 20 times or more, adding water, stirring it, empting it, repeating that, it the water just eventually turns clear, then I knew it was clean enough, and added it to the tank, then did the other half, i spent about 2 hours, just stirring the sand cleaning it up, I think it turned out pretty good, I ordered me a nova extreme light fixture, hope it looks good, only got it for $79.00, lol, not to bad.
