I would just like to say thanks to everyone here for your knowledge and assistance with my introduction to pool care in our rather humble pool. I was fortunate enough to have found this site and acquired a great test kit before getting started. The result has been a crystal clear and sanitary pool for the whole summer. I did not have even one incident of concern about the water. Just stayed faithful to the BBB method and enjoyed swimming all season long.
My pool is now closed, which for our humble operation involved folding it up and putting it into storage containers. Next year I'm going to upgrade to a sand filter for even better results.
Thank you all for your insight and assistance.
