We just have the Intex vinyl 15 x 36 pool and after filling from my well, with an rv water filter attached I thought it was pretty clear. Then I waited a day, and it was orange. I started filtering with poly batting in the included skimmer, and put a white cotton sock filled with poly batting on the return end after it filters. I changed and rinsed clean the poly and sock for several days. Then I added 4 cups of bleach and it went all ice tea looking again. I have filtered the last two days, and my water is clear, crystal! I will run a test kit and add more bleach if needed and hope it doesnt turn brown again, but it really works! Its been raining for two days, so will wait till that stops to continue. thanks for 5 gallon bucket, poly fill idea!!
