Got this pool for my grandson and want to be sure the water is right for him Filled 1,052 gallon pool on Monday and put chemicals. The pool pump has run for a total of 12 hours in the last 24 hours. Tested the water ta200 free chlorine 3.0 total chlorine 3.0 pH is below 6.8 I'm assuming I need to add soda ash but I don't know how much to start with for my size pool Tia for the help
 
Welcome to the forum!
I suspect you are using test strips as the TA of 200 with a pH of 6.8 is not chemically compatible. Do NOT add any soda ash. In fact, never use soda ash.

I'm using a test kit with liquid drops that tests Total alkalinity,Ph,Free Chlorine,Combined Chlorine,and acid demand. Last night TA was at 140 after adding muractic acid. Pump ran overnight for 9 hours The Ph is below 6.8 this is lowest on vial comparison. Guessing here Ph 6.4 or lower. I'll keep the baking soda for the kitchen LOL
