I recently bought a house with a 15' round 4 foot deep pool. I finally got most of the work done on the house and now it's time to focus on the pool. Originally it was swamp like but I have been using my leaf eater and skimmer to try to clear some of the gunk out. Now it's more blueish green with a dirt film. I hooked up my pump and sand filter up to the pool and my pool is almost ready to finish filling up. What do I do now? I tested my water and there is no cya, so I bought some stabilizer. I assume I need to finish filling up the pool, turn on the pump and filter on, do I need to backwash it a certain amount or anything? Then I assume I need to add cya. I'm not entirely sure how to add it, some say pour it in the skimmer some say use a sock, what's better? I have granule stabilizer. I also need to vacuum it, when is best to do that? Should I be running the pump and filter 24/7 till my pool is crystal clear? Once my cya is up to 30-40 I can slam it. Just need some advice getting to that point. Thanks so much in advanced!
