ok so i have a 15000 gal intex ultraframe with sandfilter and swg. we had to drain it over the winter and it's time to refill. since we live in the country and water is high here we fill it from our creek. I have filled if from the creek before and did get the water crystal clear after an investment in time and chemicals so i know it can be done. my question is, i found a post on the internet where someone filled their pool by pumping through their pool filter and the poster said they filled through the waste port of the filter and water filled the pool through the skimmer. so im wondering if this would be effective way of prefiltering the water and possibly save some time and money? any suggestions? i think the original poster was "duraleigh" any help much appreciated.
