TA to low

[mrsmith65]

I am trying to raise my alkalinity. I have no reading, the 5 drops of alkalinity indicator it is suppost to turn green. Mine just stays red, I have added 28#s of baking soda in the last 24 hours an still no change. Please help, am getting a bit frustrated here. Thanks for any reply.

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.
