First off-welcome! This site has been a godsend for me with caring for and maintaining my pool. I have learned so much and so far I am three years with a sparkly pool.
Second-read pool school and then read it again. Learn to understand the CYA to chlorine ratios, find PoolMath to help you with your calculations, get the tf-100 test kit (it is worth it, I promise).
Third-a quick check of your pool chlorine every day will keep you from the green monster. It takes less than a minute.
Fourth-if you have any problems, ask. There is at least one person here who has has the same problem. You do need tough skin because the answers are no holds barred and blunt and occasionally come off as rude to an unsuspecting person. The people here sincerely want to and do help.
Fifth-it isn't going to work if you take some advice from a pool store and some from here. The people here have nothing to gain except the owner of the tf-test kits. The pool store has much to gain by selling you many chemicals. The people will help you here with advice and education free of charge and are glad to do that. That all being said, I did donate to become a lifetime supporter because I found the value of this website to be worth much more than that and maintaining this forum takes a lot of work. No, I have no idea who Dave or whomever actually runs this is.
Happy summer and enjoy your pools!
