So long story short, several things went wrong over the winter and I found myself faced with a very green pool. After a few days of slamming the pool, brushing, and running the pump 24x7, it is starting to clear up. My question is whether or not I should replace the water once it is fairly clean. The reason I'm asking is that I saw little organisms in the water when I first uncovered the pool. I'm guessing that all of them were killed by the bleach and that most if not all were filtered out, but still feel a bit queasy knowing that they were in there in the first place. I have a vinyl lining and I've read that it's not good to drain all the way, so wondering if I should or should not risk damage to the lining to replace the water. Any advice would be appreciated. Thanks
