Halfway through acid wash on 17K gal pebbletec swg pool. Prepping for the renaissance. At moment looks like 0 TA and ph well below 5, chlorine somehow disappeared. Anyway, since borate seem to be advocated here so much, would like to add that to my balancing. Iam seeing on some threads that baking soda can be added to begin rebalance process. Am thinking I will use borax first and that would offer much bring up the ph and ta as well as add borate. Then I can fine tune ph . Does anyone have any thoughts on this? According to pool calculator if I add 640 oz of mule team I will take ph and Ta to almost near target and borate s to 34 . Is this a good idea or if not, why? Thanks for any input given. I am only a couple years into pool ownership. Still learning!
