You don't need any Borax or baking soda as your pH and alk are fine. I wouldn't add any more or test for CYA again for at least 4 or 5 days to save your reagent. And, that way you'll have given that last bit of dichlor time to have totally dissolved into your water so you should get an accurate reading. How does your water look? Is it all clear? Did you get your test kit yet?
