The most critical problem you have right now is low pH as any reading below 7.0 is acidic and can damage your pool! We normally recommend using 20 Mule Team Borax (laundry aisle at Walmart) to raise the pH. However, since your alkalinity is also low, you can use Arm and Hammer washing soda to raise both at the same time. Add it slowly to the skimmer, breaking up any clumps, while the pump is running. I'd start with a fourth of a box at a time. Wait a few hours, retest, redose until you get your pH between 7.2-7.8 and your alk between 80-120 or so. (Just an FYI, if you need to raise pH only and not alk, you use Borax.)

Also, get some bleach in there per Ben's instructions before it turns green!

By the way, you can work on pH, alk and chlorine at the same time. No problem.

Good decision buying the good kit. As soon as you get it, post a set of testing results. We really need to know the CYA level to pinpoint our advise more accurately for your pool's chlorine requirements.

Let us know if you have more questions.
