We bought a new house in April and it came with a beautiful backyard and 4 year old above-ground pool built into a paver deck. We had no idea of the pool condition but did not trust the previous owners when they said all we had to do was remove the cover! Turned out the cover had holes in it so when we opened it like 3 weeks ago it was filthy. For the past 3 weeks we have been getting our water tested at the local pool place...doing exactly what they said...and they have been telling us for about 10 days that our chemicals are perfect. Problem is this: the pool is blue but cloudy...and when I vacuum (almost every day) the return seems to be spitting dirt back out! We have a Hayward sand filter...anyone have any ideas of what could be causing our problem?
