Allison, welcome to the forum, it's a sincere pleasure to E-meet you First, the only dumb question is the one unasked!. Second, Poolguy's advice should be listened to (the link he gave you said exactly what I would have ) Third, I realize that being a new pool owner can be frustrating and confusing, the BEST thing for you to do is to go to PoolSolutions.com and read everything there, it'll 'catch you up' to the other folks here and give you a very solid foundation on pool care. If you ever have any other questions, all you need to do is post and the great folks here will bend over backwards to help! Again, welcome - Waste
