We have an Intex 14 X 42 metal frame pool, salt water filter. We started to fill the pool, left for half a day, came home to find the pool brown. We came to find out that they flushed the hydrants in our area. We ran our filter 24/7, rinsing the filter every hour during the daytime. We also used the sock method over the outflow and rinsed that out every hour. After the fifth day I caved and went to the pool store to get something for the water. The gentleman at the store could not guarantee that it would work and suggested I drain the pool and start over. So I went home and did just that, but before I refilled it I put a sock over the hose that was filling the pool to find that the rust was still coming out of the hose. What we ended up doing is using four socks and two microfleece shamies that you dry your car with and put one inside the other and stuck the hose inside the socks and fleece and rubber-band them together. Every hour I went out and rinsed the socks out and then put them back on the hose and put the rubber band back on and did it all over again. Needless to say, it worked and our water is crystal clear. This story probably won't help you guys who can't or won't empty the pool, but hopefully it will help you guys who do not leave your pool up through the winter and have to fill it every year. Just initially put a sock over the hose, turn the water on, and you will see if there is rust in the water. I can guarantee we will be doing it every year.
