The reason for adding Borax is because Dichlor is very acidic and will drive the pH down. If you are just going to use bleach, you may or may not need the Borax. Just test and determine based on the readings.
Got it! I'll sit on the Borax for now. My pH is sitting at 7.5 right now so I think that's about right where I want to be, correct?
