Hi Gracy and welcome to the forum. You've gotten a lot of good advice so far. One thing I would like to add.....go to the sister website of this forum www.poolsolutions.com and read EVERYTHING (and I mean EVERYTHING) on it that you can. Some sections need a password but don't worry about what is in them...just read all the rest of it and then re read it. Once you have finished you wll have a very good idea on how to take care of your pool. If you don't understand something then start a thread in the proper section of the forum and the good folks on here will help you to understand. Then read all the 'stickies' in the forum and read as much of the forum posts as you can. You will become a 'pro' in no time at all!
