Okay so I had this conversation with a guy at work today. He jumped out the pool to ask me this and this is how the conversation went.
Him: Excuse me, how much chlorine is in the pool today?
Me: About 4.8mg per square metre, I just checked it and we're lowering it gradually, but don't worry this is well within the limit.
Him: Do you not use any other cleaning method?
Me: No we use the chlorine and acid combo
Him: That's so old fashioned
Me: Really? I thought most pools used this, certainly the ones I've been to and worked at have.
Him: Well, no they don't, a place as modern as this should be using ultra violet cleaning.
Me: Never heard of it.
Him: The chemicals are horrible, all the chemicles in swimming pools are responsible for the number of cancer sufferers in society today
Him: I wont be swimming here again, or joining the gym.
Now obviously he's going way over the top, but is there any way that using chlorine/acid combos in swimming pools could be linked to any form of trigger of cancer or anything? Seems a bit of a silly idea being as the majority of pools use it....if it was so dangerous then they wouldn't use it right?
