First thank you for this comprehensive post. I’m sure it has helped a lot of us.
I have a couple of questions:
You mentioned testing after half an hour. At an average flow of 50 gpm
only 1500 gal of water circulate through the pump. What is the value of the measurement if we know for sure that the pool water hasn't been fully circulated?
You suggest to add each time to shock level, and you also mentioned to "hit hard".
If we see that this is not just a bloom, but a swamp, isn't it better to start hard indeed? What should be the starting point?
