how much borox and how long to wait after adding to swim

Without knowing the actual number we can't possibly tell you how much to add. You can use the pool calc to figure it out once you have a number.

If it's much lower than 6.8 you should test the TA to make sure it's not terribly low and then use 6.8 as the starting point and add enough to get to 7.6. you may have to add a few times if it's really low.

Once you get it into range you can swim.
