Any new updates that anyone is aware of concerning borates and dogs? I'm thinking of adding borates to my pool as I've had a terrific experience with it in my spa. But my dogs do swim 30 minutes 2-3 times per week in the pool, so just asking.....seems like the posts from last year reflect a high degree of safety for dogs at 50ppm. I'm thinking of just trying 30ppm and see if that's good enough for me. Any reason why I shouldn't try at 30ppm?
