Your pH is fine, so no Borax needed tonight. As long as your pH is 7.3 or higher, I would skip the Borax.
Since you lost 4ppm of chlorine in the past 24 hours (since your CYA is still pretty low), you'll probably want to go ahead and add some Dichlor this evening. Don't want the chlorine level to drop to 0 tomorrow and risk algae in a new pool!
(As you use Dichlor and your CYA level builds up, you'll find that your chlorine won't disappear as fast.)
