Does a pool with a strong chlorine smell mean there is loads of chlorine and its healthy to swim in?

The smell comes from chloramines which are the by-product of chlorine acting with some contaminants in your pool water (such as sweat, skin cells and urine). Chloramines are the toxic by-product of incorrect chlorine sanitation, they can irritate people with allergies, asthma and skin sensitivities such as eczema and psoriasis. Ozone water purification is effective because it specifically attacks and removes chloramines from your pool water.
