I have a 21ft by 4ft above ground pool
I opened it a week ago last Thursday and still can't get it clear and blue
Opened as normal,vacuumed all chems were great, pool still green
changed sand in filter,pool still green
tested water and had very high phosphates,used 3L of Phosfree - the next morning it was turning blue but was still cloudy. By supper it was green again.
This morning it's neon green again.Chemicals are great
I just don't want to keep throwing money into a pool that will never get blue. Help please
