I need some help. I had a little black algae starting to pop up. I went to Leslies. They gave me black algae killer. I put 1qt 6 ounces in . Then scrubbed for 2 hrs. Then added phosfree and ran for 2 days. I think all algae is gone and the pool is crystal clear but there is this lingering smell and foaminess to it two weeks later.
