I bought my house in May but it was my grandma's so I've been taking care of the pool for 20 years already, albeit poorly I've come to find out since joining the forum. Anyway, I'm certain she is doing violent somersaults in her grave because I haven't closed the pool yet. She would have been talking about closing at the end of July after the bummer summer we had in Michigan. But I'm holding out for 60 degree water.
On a side note, I've been taking care of my 80+ year old neighbor's pool since mid summer. The pool had an algae bloom. She is on oxygen and the dichlor granules were hard on her...and the pool. Her family was closing the pool this weekend and told me they don't think the water has ever looked as good as it has the last month. Quite a compliment since the pool is circa 1969.
