So I had a dream that there was a 'new this summer' inground pool. It developed had an algae problem, similar to the story in this thread and of course I went to put all my good TFP knowledge into play.
Still dreaming, I realized that I had not brushed the new plaster daily, or kept a good watch on CH, or even pH!
So I was running around in a panic, yelling for a brush, and where was the test kit, and why oh WHY did I not practice what I preach here at TFP....
Then I realized that not only was the pool vinyl, it was my neighbors!
