I have a 30,000 gal pool. It has been unused for a year or two by previous owners. It's in ground with a vinyl liner. It has a sta rite cristal flo sand filter. I used a whole bottle of HTH floc last night, recirculated for 2 hours, and then let it sit for 12 hours. I have a film of brown patches cover the entire top of the water. Per my local pool store, my levels were the following.can you please help me.
