No Cyanuric Acid?

I test the pool with a test kit, not the bonk strips.

I put in 1.5 ish gallons of bleach last night, plenty of Chlorine this morning. I'll test tonight to see if there is any left. It's gonna be plenty sunny today.

If you used the 'cloudy water' test for CYA (melamine precipitation), and got a zero result . . . it's zero. The remaining question is, did the CYA go to nitrogen gas (no problem) or ammonia? If it's ammonia, you'll see high combined chlorine levels, and low free chlorine. You have to use a DPD test kit to get good info on that.
