I bought the TFP salt pro kit to start testing my water more accurately this season. Pool was recently opened, and the deep end has a green tint to it - can see clearly to the bottom. 18k gal inground pool.
First test, CYA = 0. I could see the metal circle at the bottom perfectly even when the cylinder was completely full. CC = 1.5, FC = 1.5. So, I followed the SLAM checklist and used the pool math app. I added the required stabilizer in a large sock, hung it in front of a return yesterday morning, and by late night it was fully dissolved from the sock. Ran the pump overnight. This morning I tested again, and CC = 0.5, but FC went to 0. Tested CYA too just to see, and while definitely cloudier this time, I could still make out the metal circle even when full - but it was certainly getting less visible.
So, pool math app told me SLAM FC = 12, so to add 1.7 gallons of 12.5% liquid shock. Did that, and tested again at 12:30. FC still 0. Added another 1.7 gallons of liquid shock, tested again at 1:30. FC still 0.
What am I doing wrong?
