My FC today tested 14. and CC .5. It has been over a month since my SLAM and the FC fluctuates between 7 and 14. My CYA is 60. Pool math always tells me to add stabilizer and I do. I don't understand why the stabilizer is always low with such a high FC. I know from reading that I can't get an accurate PH with my FC that high. My TA is 100. I run my SWG at 75% and my filter 24/7. Should I cut them both down? My pool is clear.

The only way your CYA is going down is due to overflow from rain or a leak. Are you adding water to the pool?
It would be great if you entered and saved your test results in Poolmath so we can see them. You are sharing your data, but no test results are in it.
Your SWCG is creating 5.7ppm FC each day for your pool volume. Keep your FC in the target range for your CYA, see FC/CYA Levels

2 and 1/2 inches of rain 2 days ago. 3 inches a few days before that. I thought I was saving my logs. There is no way to get my FC down and we do have lots of sunshine and the pool gets full sun all day. I do check the chart but it never has my amount of FC/CYA on it or am I just dense? I have no idea what my target FC/CYA should be. Lol! Do I need to lower my SWG %?

Can you open the link I posted?
Overflow can reduce Cya. A few inches out of a pool does not have much effect though.
Lower your SWCG setting to 60% and see what happens.

Sorry had to take a neighbor to the store. I will lower to 60% and go to the link you posted. Thank you!
