The trichlor pucks are acidic and are driving your pH down. Continue to work on bringing it up. Washing soda will raise pH and alk whereas Borax mainly affects pH. Adding it slowly through the skimmer while the pump is running is the correct way to do it.

What is your chlorine reading in the evenings when you test (but before you add bleach)? How much chlorine are you losing overnight?

Go ahead and test the CYA level and report it. You can always buy refills on the CYA testing reagent.

My CL readings at night are between 1-3ppm, I then add 3-5 gal of bleach, then it is then 5-7 on average with CC 1.5.

My pH was 6.8 today and TA was 140 the last I checked. So it sounds like I would be better to stay with Borax so I dont get my TA any higher. My jets are aimed at the surface to raise the pH but that has not seemed to work for me.

Is there anything wrong with adding bleach through the skimmer? I normally add at the return jet in the deep end.

Oh, do the 3" pucks from Sams club raise CYA?

Thanks,

Mike
