Why would you add R-0006 to the pH test? If you did the test correctly and your pH was below 7.0, adding Borax was the correct step.
Did you run the CYA/Stabilizer step? I assume by CA you mean Calcium Hardness, not Stabilizer, but if it is stabilizer, then you should ONLY use bleach in your pool, and use enough to raise your FC to 25ppm. If it is the Calcium measure then you need the CYA measure so we can determine the level of shocking you need. In the meantime, you should add at least 154 ounces of 8.25% bleach and get your FC up to at least 12ppm, and keep adding bleach to keep it there, assuming you have little or no CYA.

If the "HTH 6-way stick" is a chlorine tablet, stop using it. Use only bleach. If it's test strips, stop using them, too.

Need that CYA number and a good, current pH measure.
