I am interested in adding borates. Of particular interest in my case while researching was this quote from waterbear's post above:
We have a Golden Retriever that does currently think the pool is her own private water dish, and has been drinking the majority of her water from it for 5 years, as we didn't know it was bad for her (although we have always prevented her from drinking immediately after adding any chemicals to prevent her from drinking any high concentrations of anything before it has time to blend well). Can anyone provide or point me to additional, more specific info on the hazards of pets drinking pool water, both with and without borates?As far as dogs (or people) ingesting small amounts of pool water, that's not going to hurt then BUT if you dog things the pool is their own private giant water dish that is NOT a good thing, borates or not! There are may chemicals in our pools that are not really good for our pets to consume in large quantities! Provide fresh drinking water outside and change it regularly and it's pretty easy to teach your pets not to drink from the pool! (I know a bit about this, I have three dogs and a cat!)
Also young ladies using our pool often want to know if I've shocked the pool recently in fear of turning their hair green after they've recently had a "perm". At what chlorine level is there risk to tinting someone's blonde hair green? I have noticed during some years that the blondish hair on our dog's belly will turn a slight green tint, but she essentially lives in the pool compared to human users. I ask because I switched to BBB this year, and one of the differences is the recommended chlorine level is around the high end to a bit higher than the pool store program we had been on in past years, especially if CYA is a little high.
