So I just got a 125 gall tank today from craigslist. The tank is acrylic and has been drained for a couple weeks. The tank came with about 100lbs of sand in it. Can I rinse the sand in the tank and then vacuum out the water with my python or do I need to take all of the sand out and clean it in some other way? Also, it came with a light strip that seems kind of small. What are the lighting options for an acrylic tank? It will be fresh water with no plants. This tank is pieced together like a regular glass tank with a wierd top that has 2 large and 2 small rectangular holes in it. I would include a pic but I can't get my camera to work.
