Heavy Rain

[doloskeeter]

Thank the good Lord for 3.88 " of rain in Mesquite, Texas!! In anticipation, I bumped the chlorine up to 8 ppm last night. I carry a CYA of 40 and target 5 PPM on a daily basis. We had to drain four inches this evening because the water was up to the coping -- PH is 7.5; FC is 5 PPM, CC is 0.

Should I leave chlorine level where it is or jack it up to 8 PPM due to the heavy rain. We're back to sun at least until maybe Monday.

Thanks for all your help!

Rain has far less influence on your pool than most folks think. Keep your target FC at 5 ppm.

But check your PH--heavy rain drives mine up with all the aeration. But yeah-we'll take the rain!

With a heavy rain like you received, it is entirely possible that lots of dirt/debris was washed out of the atmosphere and off of the patio into the pool. That's entirely normal after a downpour like that, especially after a prolonged dry period. Consider giving your pump/filter as well as your Polaris a bit more run time to clear that up. As others have stated, keep FC at your current target of 5 ppm.
