No specific problem, just preventative I guess… And wanting to drink the best water I can get.
Once I was convinced that I needed to drink a couple of liters of water a day just to stay normally hydrated; water being our next most important nutrient after air and after several water experts concurred that BG bubbled water was the best they’d ever tested (for ORP, frequencies, pH, etc.) and I already had BG machines… it just naturally followed that I’d bubble the water I drank.
