Thanks again to everyone for all the help on here!! You are all wonderful! I don't remember the last time my pool looked so good. It is the first summer that I have not had algae climbing up my walls! I have been maintaining levels, sometimes they get down lower than I would like them, but I bump them back up. My pool has been beautiful all summer since doing the big change over. NOW, I am leaving for 4-7 days for the beach, what do I do with my pool, to ensure it stays clear. I have a friend I can ask to come up and put bleach in for me. Thanks for the input.
