Hey all!
Been a long time follower here and utilize all the resources, including Pool Math. My main question is: On a Hayward T-15 Salt Cell, all the numbers on the panel look good and readings are correct, but is there another physical way to test to see if the salt cell is producing chlorine?
Background:
My original T-15 Salt Cell died about 1 month ago. I went and bought another one for $1K (ouch!), re-installed and had it up and running per the controller. Everything is honed in, but now 2 weeks later I found myself with a pool full of yellow algae and 0 chlorine. So this past weekend I went ahead and performed a SLAM, had ~60 CYA so brought my FC up to about 20-23 PPM. 2 days later of the SLAM and I passed all the tests, including the OCLT.
Since I was in the clear, I turned the salt cell back on to ~60% (pump runs from 8AM-4PM) and all the salt cell readings are clear. Now, about 1.5 days later from passing my OCLT at 22PPM, my FC is reading ~14 PPM. I know FC falls off when it is higher, but didn't think it would fall off that fast.. if the salt cell is working? I am in central Florida and hitting 85 degree days + running a solar panel.
Is my best bet to test the pool at 9PM, run the pump overnight and run the salt cell at 100%, then test again at 7AM and see if the FC went up, to prove the salt cell is functioning?
