As the dog days are upon us, many are reluctantly thinking of closing their pools. So, to keep us on our toes I have a sand filter question.
I was reading a PF post that talked about adding pea gravel into the filter first. This got me to thinking - has anyone tried a progressive sand addition. Pea gravel, size 1/2 sand, 12x20, 20x40, topped off with a little DE??
In my filter, I have 100# of 12x20 and 100# of 20x40 on top of it. If I would have read the suggestion to put pea gravel in first, I probably would have. Perhaps on the next one!
I would like to hear some thoughts concerning this.
