So if I understand you correctly, I throw in 4 pounds of Arm and Hammer, and that will raise my alkalinity in my 44,000 gallon pool to where it needs to be. As a result of this, my Ph should rise along with it. Is this correct?

Also, any ideas why I showed no combined chlorine? Is this the way it's supposed to be, or do I have a problem? Did I conduct the teat properly? Lastly, this is the first time I tested for CYA. Are the numbers for that good, or do I have a problem? Thanks !
