You can ignore the BR (BROMINE) number of the test kit. Add a box of borax SLOWLY to the skimmer, if you have one. If not you can just pour it around the pool. Also put a quart to quart and a half bleach in. Borax and bleach don't react badly so you can do one right after the other. About an hour after adding Borax, check your pH again and keep adding 1/2 box at a time until your pH is at least 7.2, low pH can damage liners.
