If the TA test turn red immediately, then this means that your pH is 4.5 or lower which is WAY TOO LOW. What does your pH test show -- is it very yellow (it probably only reads down to 6.8 )?

You need to add pH Up to the pool to get the pH higher along with the TA. At some point, you'll get a TA reading and if the TA gets to 100 ppm or so you could then either use 20 Mule Team Borax or aerate the water to continue to raise the pH until it gets closer to 7.5.
