Hello, my pool was completed just at 2 weeks ago. I have been adjusting my SWG sanitizer output down. It has been at 60% for about a week, we had a party yesterday, lots of people in the pool. Today FC value is 12, so I have turned SWG down to 40%. ((FC had been trending down since startup of pool: 15 --> 12 --> 9 --> 8, but then now up to 12) This week we had heavy rains, so I think my CYA has been diluted out somewhat. My owners manual for SWG says ideal salt level is 3400ppm. My water looks good, crystal clear.
Here are my numbers:
1. Regarding FC: Is this what I need to do. Adjust the % down, or should I maybe adjust the time it runs? See question 2.
2. My pump/SWG is on a timer. We are currently running it 8am to 8pm. If we cut the time down, would that help decrease the chlorine output?
3. Per pool calculator, I need to lower my pH and add cyanuric acid. Should I raise pH first, then add CYA? Should I retest CYA first after raising pH?
