Nature2 stick and Bromine

I just fill a new hot tub 5 days ago and let the Nature2 mineral stick in it while I used bromine sanitizer. I realized u shouldn’t have done that and took the stick out. Do I need to drain and refill since it was only 5 days? My hot tub also has an ozone system. Is ok to use bromine sanitizer with this?
