you can buy a better tester that does go that high... ( I even have some "guess" strips that go higher).

If you don't mind dumping, cleaning, & refilling... then yes, it probably is easier ( & faster)... especially since your TA is a bit high.

If not interested in going that route, then use the bleach calculator & test as frequently as you can.
It does take time. waiting is so hard

Good Luck
