I'm in a similar situation. My new pool was built three weeks ago, and my ph can jump from 7.6 to 8.0 overnight. My CH is around 200 presently... and I've kept it there because my CSI would be much higher if my CH was around 300 during one of these jumps.Originally Posted by waterbear
Is my logic faulty? Even if my ph frequently jumps and my CSI would be higher, should I still have a CH of around 300? Or should I wait until my ph is more stable before raising CH further?
