I just emptied and refilled my hot tub. It is a royal spa ~450 gallon hot tub. I add a package of instant bromine reserve, chemical to remove metal, and shock. Let the jets run for 30 minutes. 4 hours later I tested the water and not 100% sure on all the results.
Bromine 10. (Need to remove float with bromine tab until bromine level drops?)
Ph was 7.8 to 8
I know Ph is boarder line high as well.
Any help would be greatly appreciated.
