the pool is still beautiful. I wish I'd had wherewithal to do a real and complete SLAM much much earlier. I cannot believe how clear the pool is. I can see the bottom of the far end. That's never happened before. And I have not had to clean the filter once, and the flow and water pressure have held stead. The real test is that friends and family enjoy it now (without cringing). Great advice here in these forums. That's why I became a TFP contributor.
