bart6453 Posted November 15, 2009 Report Share Posted November 15, 2009 So I did a refill today and was checking the water before it went into my tub. Here are the readings.. PH=8.2 TA=50 FC=trace CH=150ppm So with that said, how can the PH be stable at 8.2 with the TA so low? In my tub when I put the water in and add borates, it reaches a PH of 7.5 in a matter of hours with nothing else added. Why does it maintain such a high PH in the pipes and water supply but when I put it the tub it drops. Is it because the pipes are a sealed, pressurized system and it does not allow outgassing???
