I stumbled across this site about two weeks ago, just before I left on vacation for a week. I had just received my K-2006 test kit, but hadn't gotten around to using it as I was experiencing a leaky pump and trying to deal with that.
Now that the pump is all fixed, I began TFPC a couple of days ago. I am SLAMing today as I have a good bit of yellow algae clinging to the walls. Just for the heck of it, I did a OCLT and found my FC went from 9 to 5.5
Our spa returns over several rows of rocks into the pool and that particular area is an algae breeding ground. It's very tough to scrub in there and get up between the layers of rocks
I have come to really appreciate the Pool School and Pool Math calculators and now have my own online log setup via Excel Online to track all measures and log the chemicals added. I never appreciated the need to keep the pool clear of debris and how that plus bather load will impact FC and the overall clarity and cleanliness of the pool. I think my family is in for a "shock" education on swimming pool behaviors.
So just a big "thank you" and would appreciate any advise on how to keep those rocks maintained clean and algae-free
