![]() A few potential causes (I fought off sleep and read through several gargantuan threads on RC!):
1) High (organic) phosphates? 2) New house, new area, new water source/water treatment plant? Some use Chloramine? 3) Salt mix. Did you switch salt mixes? I just read that some salt brands are using many times the natural amount of Borate in order to keep the mix in solution. As I understood/read it, high levels of Borate skew test readings for Alkalinity (ie. the true dKH will be much lower). |
