No, you don't have do another K2006 test.
As long as your pool is clear, just add a gallon of bleach each PM, till you work out a plan. Your pH is pretty low, so you should probably also add a box of borax -- slowly, to the skimmer, with the pump on.
Get a cheap OTO / phenol red kit for quick tests -- skip the bleach dose if the OTO test shows dark yellow or orange.
Meanwhile, you need to decide what's next. Dichlor is a chlorinating powder that adds 9 ppm stabilizer for every 10 ppm of chlorine. It's very soluble and easy to add, and is the basis (with borax) of the SS recipe. You can get it at Sams Club quite cheaply:http://pool9.net/sams-dichlor24/You *may* be able to find it at Home Depot, Lowes or Ace Hardware -- look for a dichlor that has at least 56% "available chlorine" and NO copper listed.

Eventually, you have to stop using dichlor, because your stabilizer will get too high. But for now, you can use it, along with borax, to maintain your pool.
