About 1 month ago I finished installing a Jandy AquaPure 1400 on my 25k gal IG gunite pool. Mine is connected to a Jandy RS8 & was a snap to install. I shocked the pool with bleach first & now I’m running the AquaPure at 8 hours a day & at 75% output. Yesterday I had CL at 2.0 & the amount has been gradually climbing, so I’ll back off the output in a day or so when it reaches 3.0.
