If you have a good pool cover, debris should be minimal. Pour it into the water as you walk around the perimeter of the pool, and then circulate the water for six to eight hours. Brush down the sides, steps, and ladders, making sure to get into the corners and behind things that the vacuum can’t reach.
You are suppose to shock bromine pools with chlorine, just make sure not to mix the two chemicals, and do not add to much chlorine.
