My name is Carla and my husband and I have a roughly 15 year old AG pool. We are the second owners and the original components are slowly needed to be replaced. My husband has been opening/closing and balance the chemicals since we moved in back in 2009. I have offered assistance so I decided to join a forum to learn how to best help balance chemicals. Our current project is to balance chemicals after the liner is replaced on July 1st. We both both beginners with pool ownership even though we have had the pool for 6 years. We are also very exciting to learn from the pros and other newbies!
