it wasn't breathed, it was properly swallowed. i just thought that it might result in upset stomach, vomiting etc but wasn't sure of chemical reactions in the stomach ie excess acid, or if the solution in pool water is very weak so as not to be a worry.
When playing with our children in our pool, we swallow more water than you can imagine, and we're still around!.....as Sqad said just spluttering and coughing!
At worst, slight tum ache that will quickly pass.
When I swum my 2 mile badge when I was a kid I think I swallowed most of the pool! I was ok though. I was a bit sick but I think that was from just the sheer amount of water I swallowed! It won't do you no harm at all.
