Well guys as the title says, I am now sold on this method. I have to admit I was a skeptic last year after going through an entire tf-100 kit and about 80 gallons of bleach trying to complete my first SLAM. I literally took my cover off at 4 pm today, about 3 hours ago and after 1 vac to waste, this is where I am at.
As you can see, I have another issue(sand)....but that's another story. Water is about 90% clear and my initial readings are FC 2.0 CC 0 and pH 7.2. In 12 years of opening this pool, I have never been able to see the main drain. Kids asked me when they could swim, I initially said middle of next week. Guessing that may change. Thanks everyone.
