Well from my most recent experience,( last week) I would most definitely find someone who has a knowledge of pool care and understands the importance of chemical balance. I left for a five day vacation with the assurance from my BIL that the pool would be the same as I left it when I got home. Was it? Not in the least, I came home to a green pool on Sunday, several gallons of bleach later, it's blue again but very cloudy, I am very upset about this. So get someone you TRUST implicitly to take care of your pool!!
justmy two cents!
