I wanted to lower the salt level in my pool and the CH some. My ic-40 is set at 8%, pump runs 8 hrs per day.I put the pump on the cover and the hose into the pool, we recieved approx 3" of rain. Here are the old numbers and then the new.
As of this am, I didn't check the cya.
The results were somewhat what I expected. I plan on adding another dose of cya to raise that some. My worry is now the csi is -.79. I know the value of csi is debated. Should I do something about it?
