Trying to help a friend. His TA and PH are out of wack. TF-100 Test numbers
TA=Was pink after adding the two drops R0007 and 5 drops of R-0008 does this mean less than 10?
How do I tackle the TA and PH? The pool is 13000gallon Above ground liner non SWG. Should I bring up the TA with baking soda using 183oz indicated in pool math than bring the PH up with borax? Never had to deal with TA and PH this bad.
