So I just opened my pool (16 x 37ft, ~20K gallons) yesterday and It was the cloudiest that I have ever seen. This is my 2nd year living at this house. The previous year's opening was really easy with the water being very clear. Although last we had a permeable loop-loc cover installed which replaced a tarp.

I tested the water and added bicarb, pH-up and shocked with 4 gallons. Retested water the next day and the results were within spec except for the cloudiness. Been running the sand filter for almost 24hour with no noticeable improvement. I've heard mixed reviews of classifiers and flocculators, nonetheless, I'm really tempted to use them.

Two questions

1) Should I give it wait and see if the filter clears things up or just go ahead and use HTH Clarifier Super Concentrate
2) This is the 1st year with the water permeable cover and I was wondering if the cloudiness was due to that.

Thanks

Chris
