I moved into a house that has a hot tub and am new to the maintenance routine. We are using bromine tablets with chlorine and for the last few weeks it's been fine but I tested this morning with the 4way test strips and it's showing high bromine and hi ph level. I have ph increaser but not decreaser so don't know what to do about that and don't know how to lower the bromine level. Any help would be appreciated.
