A few questions:
1. The Spa Frog directions say to establish an initial residual of 1-2PPM of bromine or chlorine using brominating concentrate or chlorine shock... which one is best to use?
2. In the case of chlorine shock, I thought that shock revived existing chlorine... can shock be used to increase chlorine level if no chlorine has been added?
3. Do I need separate test strips for bromine and chlorine? (If I'm establishing the initial level with chlorine, then maintaining the bromine level, for example...)
Thanks for the help!
