If you seen my build thread my PB has to empty my 3 day full pool in the next week or so to replace tiles. Concern is he is not worried at the water until after that. My reading are so off I can't get #'s to add to Pool Math to know what to do, if anything. Need help from the experts here. (lost faith in my PB or i'd call him)
2 readings same results. Water temp 54iss
CI 0
BR 0
PH can't read its yellow off the chart
CH 275
TA turns red with 2 drops of R-0008
CYA 0
I take it I need to add baking soda fast, but how much?

Tap water

FC .5
CC 1.5
CH 750 (? How blue is blue?)
TA 120
CYA I could not get the drop to go away.

pH?

I have to question your testing methods as CH 750 fill water will not become 250 in the pool.

CYA will never be in fill water. CYA does not naturally occur in water.

Municipal water supplies always have a bit of FC but should not have much CC.

It looks like the builder probably added a lot of acid to the pool.

What does the builder say about the chemistry?

CC is common in supply water. Utilities often add it to the water.

Fill water was my first test and I know the CH was way off (in my build thread) I was looking for deep blue.

He is handling it. But the numbers I posted is how he is handling it.

If you want to take matters into your own hands then assume your TA is 30 and pH is 6.8. Use PM to calculate the baking soda required but then add it in small batches, maybe 1/3 at a time, run your pump on high, and retest in an hour. See how your test results respond so you don’t overshoot your targets. Keep on testing and using PoolMath to refine your dosages as you work your pH and TA back up.

Good luck.
