The training does take place in public pools, other than letting your trainers know that you have an allergy to Chlorine I don't know what they would do about it other than try to have you in the pool as little as possible. Its one of those catch situation as you have to do it and I don't think there is going to be any other way of them completing the training other than in a pool as I really can't see them taking you to the beach for a day!!!!!!!!
