I have been an above ground pool owner for 20+ years. This year has been the worst. It seems no matter what I do, I cannot get my pool clear. I can't help but wonder if it is the filter. When I set up this pool 6ish years ago (after Hurricane Ike took our last one), I used DE exclusively in my Intex sand filter. I was new to the sand filter line and after hearing my in-ground pool friends talk of using DE, I chose to do the same. This summer I replaced the DE with sand from the pool store. They told me that I should have never used DE in a non DE filter. So, I listened to them...the professionals...and bought sand. The pressure is fine, all other things the same. I have purchased more chlorine, algaecide, baking soda, clarifier, and Leslies brand of chlorine, than ever before and to no avail. Even when I get the pool to a white cloudy state, vacuum the bottom to waste, I still have a cloudy pool which then very quickly turns green yet again. Please help!!!
ON a side note, the pool pump is making a very loud sound but is still pushing the water through at a normal pressure. I expect to purchase new but that is for another thread as I am considering going with Hayward and hard plumbing it in.
