This is my first post so I hope I make sense. If I follow the pool calculator, 19,000 gallons, PH and Alkalainty both low (lowest color on the stick) and I want to use A&H washing soda to raise it, I will need to use over twenty 55 oz boxes of the washing soda? (over 1100 oz are needed to raise it to 7.5). Am I doing something wrong? Kelly

Yes, you did something wrong. However, there isn't enough information here to be sure what it was that you did wrong.

The factors that need to be entered correctly to calculate PH changes include:
Pool Size
Current PH
Target PH
Current TA
Current Borate

A mistake on one of those fields could produce an invalid result. The most likely possibility is that you entered your pool size as 190,000 gallons, but that is just a guess.

Also, if you're using test strips, you don't want to rely on them for accurate testing. It would be better to get a good test kit.
