Hello. We have a 22X52 round pool by Intex. We have a 2,500 gph filter and have started using the Intex SWG. The only way we could get water into the pool was to pump from our pond. We have been running the filter and using the SWG approx. six hours a day. We have tested the salt level and it is good. The test strips we have say that there is no chlorine present. We have not added cyanuric acid. Could this be why the pool is still looking like pond water? It's still green/brown. It's supposed to be a warm weekend here and we would like the kids to be able to swim in it. Any help would be appreciated!!! Thank you.
