Higher ppm chlorine to keep clear water

[Themacdadt]

I know my chlorine should between 3 and 5. My problem is my water is clearest at 7 and 8. When I let it Drop down it starts getting cloudy around 5. All other levels are in range. Why is this happening?

Thanks

Post all your numbers, especially CYA. If you look at the chlorine cya chart, Chlorine / CYA Chart - Trouble Free Pool the only CYA level where 3-5 is recommended is 20, which is considered too low.

T,

I suggest that you run an Overnight Chlorine Loss Test. (OCLT). Overnight Chlorine Loss Test

Most likely you will fail and need to run a quick SLAM.. SLAM Process

Thanks,

Question your assumptions. What really is your CYA? How low does your FC drop at its lowest point during the day? What is your highest FC level after adding chlorine and mixing for 45 minutes?
Follow Jim' sage advice. Overnight Chlorine Loss Test Prepare yourself for a SLAM Process

Cya is 80, ta is 65, ph is 7.2 ch is 300

A CYA of 80 and a FC level of 3-5 ppm is your problem.
Anticipate draining up to half of your pool water and follow the SLAM Process

Look at the CYA/Chlorine chart.

Ok sorry I see you have a SWG. So your CYA is only slightly high for your system but you will need to SLAM.

T,

I have a saltwater pool and always try to keep my FC at my target or higher... I never want to get close to my minimum, so I do not try to keep my FC between the min and my target.. Running a little high is never a problem, while dropping too low certainly is..

Thanks,

Jim R.

I too have a SWG and with an auto cover my FC always runs high. Usually in the 7-9 range and if I don’t pay attention for a day or two it can creep higher than that. I used to fret about keeping my FC in range. Now I don’t. So as @Jimrahbe says never worry if it is too high. My water is gin clear and looks and feels great. SLAM the pool and then keep your FC above 7.

If the water looks good at 7+ FC, crank up the SWG and run FC up there. If you have a variable speed pump, it won;t even cost you much extra to do that.
