To put it simply, the water in your swimming pool becomes cloudy when large numbers of small, almost invisible particles reflect back sunlight, which creates an unsightly, murky appearance. And by small we're talking anything from 0.5 to 5.0 microns (a grain of sand is roughly 1,250 microns).
Swimart pool technicians have tested all types of 'cloudy' water, which starts off slightly dull and, when left untreated, can turn completely opaque. Here's how you can tell the difference:
Dull – you hardly notice this stage but this is when pool water starts to lose its lustre
Hazy – while you can still see the bottom of the pool, it's hard to make out the details
Cloudy – the water looks milky and, while you might be able to see the bottom of the shallow end of your pool, you're unlikely to see the bottom of the deep end
Opaque – at its most extreme, you can’t see the bottom of the pool
These microscopic particles can be caused by a number of factors, including:
