So I just tested my water for the first time. Pool is being opened this weekend. Still winterized as of right now, I just pulled the cover back to test.
1. CYA = 0
2. FC = 0
3. TA = 30
First question, I understand FC would probably disappear, but why would the CYA vanish completely? Last year I ran CYA of 65 and FC of 5 using a SWCG. I've read tons about if CYA got too high the only way to get it down was to drain. My circumstance was I drained down about 15 inches and with precipitation I had to pump some more off a few weeks ago to get the level to where it should be. Would that amount cause all CYA to disappear?
My second question is a puzzler. Last year my TA was always over 100. I worked all summer to get it down and eventually I was right around 100. I test today and it is 30???? How the heck is that? Now I need to raise TA?
Lastly, wow is that water cold. 45 degrees! Brrrrr! My hand is numb as I type.
