I wasn't questioning how I got to where I am. I know how I got here. Just questioning the best way out of a situation. I reiterated that the method DOES work - I'm not saying it doesn't. Just saying, if you find yourself in this situation, it may not always be the best method. In my case, it probably wasn't and other people may find themselves in similar situations. Can't un-ring a bell. And, yes, we've had 2 bad years in a row. 2013-2017 were all good though. Life happens!I agree with Woody's post. How did you close your pool this past winter to even get into this situation? Many people on this site posting about swamps are new owners who inherited swamps from previous owners. Simply putting a tarp over your pool during winter and basic chemicals gets you to a point of running your pump for 3 days in March/April to get it clear. The people in the South who don't actually close/cover their pools will run the pump and maintain chemicals all winter. You said you had the same situation last year when you decided to drain the pool vs. SLAM. Seems like the root cause is the lack of preparation for the winter, not the SLAM method.
