PH Levels after Newly Plastered Pool

[CarlD]

Thanks for the quick reply. I will get numbers posted later this week. I do keep the TA in check. In fact I had to add some TA up to bring levels back with in range last week. Thre was no special start up method used. But when they finished plastering they did a light acid wash to expose the aggregate. Perhaps that is contributing.
Thanks Again

I hope you realize that TA Up! is nothing more than ordinary baking soda. If it says Sodium Hydrogen Carbonate, you should know that's an alternate name for Sodium Bicarbonate....Arm&Hammer Baking Soda! And, if you use pH Up!, you'll see it's Sodium Carbonate--same thing as Arm&Hammer Washing Soda (In the yellow box in the laundry section).
