Recommended values for a SWG pool

[Charlie]

Thanks Evan. BTW, my water temp is 86°F. I wouldn't mind knowing why those values will work well when you have the time.

I've been battling the pH rise since I have a SWG pool and a spa spill over. In one week, it can go from 7.4 to 8.

I have a Pool Pilot for the SWG. Its about 5 years old now and I'm probably going to replace the cell sooner or later. I believe the manual says they last about 5 years.

Pool size: ~14,000 gallons
type: plaster with pebble tech finish
filter: DE (using the alternate substance instead of real DE - sorry don't remember the exact name. Supposedly it filters better and when back washed, 95% of it comes out compared to DE).
what I add to the pool: normally only acid and sometimes choline if I measure it and its low.
