A couple of weeks ago, I decided to empty and clean my pool. It's fiberglass, so I high pressure washed it when it was empty.
I also just got a tfp test kit and a magnetic stirrer, and took my first test today this morning.
fc ppm 1
cc ppm 0.5
fc was better yesterday, but the kids were in the pool all afternoon, and the cover was off. I added some Cl after taking this test.
I am not worried about ch since its a fiberglass pool, and I expect the ch to slowly rise.
I put in a little CYA on Thurs, but obviously not enough yet. I also know you are supposed to wait a week until the CYA test, but I did not put very much in yet. I have a sock with a few lbs of stabilizer in the skimmer right now.
BTW, the magnetic stirrer is very cool, makes it easy to run these tests.
