You would need to test daily when using bleach, at least until you get a feel for how your pool acts, and most people add bleach daily. However, since your stabilizer is quite high, it's possible that you wouldn't need to add daily but rather every 2-4 days. Again, it depends on your pool and how fast it uses up the chlorine. I intentionally keep my stabilizer on the high side at 80-90 in full Louisiana sun, and I usually add the larger jug from WalMart about every 3 days.
