Yes, Jan's right.

Usually, what you smell is used-up chlorine, called combined chloramines. It smells like chlorine and irritates eyes and skin.

Amazingly, the BEST way to get rid of it is to add more chlorine! It breaks down the combined chloramines.

I frequently have high levels of chlorine but you can't smell chlorine! If you stick your arm in the water, you'll smell it because the chlorine is neutralizing what's on your skin, which, technically, are contaminants.

The Leslies kit Jan referred to is called the FAS-DPD Service Test Kit and it's only available from Leslies on-line, not in the stores. Most pool store workers don't have a clue what the FAS-DPD chlorine test is.

If you decide, at some point, you really don't like using chlorine (and it happens) you can easily go to bromine (which seems to be better than Baquacil) or Bacquacil. But once you learn our easy methods of maintenance, you'll figure out the chlorine problems your child had were due to poor pool maintenance.
