If the pool is not covered, you'll get plenty of UV from the sun. It seems the general consensus around here is that the CORRECT UV system MIGHT be helpful for an indoor pool, but is probably a waste of money for an outdoor pool. Be sure to read everything at PoolSolutions.com. It is a sister site. You'll also want a good test kit so you'll know what condition your pool water is in. http://pool9.net/tk/

Enjoy your new pool & WELCOME to the Pool Forum. It's a great place to learn about how your pool should be cared for.
