Since your pool is freshly filled, you have the option for using the Super Simple Recipe => http://pool9.net/ssr/

One key point about pools: it's much, much easier to AVOID problems, than to fix them. New pool owners commonly get into trouble when
1. It rains, and they slack off pool care. When they remember to start back, algae has gotten a foot hold.
2. They go on vacation. That one's tricky. Ask once you know more.
3. They get 'pool-stored', spending bunches of money to screw up their pool, and then more to fix it.

Good luck!
