An interesting short article on the subject of salt water bathing in pools around the Sydney area. Clearly private pool bathing is potentially much safer than sea bathing, no stonefish, no sharks and so forth. You would have to own a small tanker to collect the seawater and bring sufficient home to keep your private pool topped up.
I think your post opens with some words missing:
'When think pools in Sydney...' 'When we think of pools in Sydney...' perhaps.
This is an interesting post about salt water. Your research is well done. I did not know that people would do such a thing as to go to those extremes to obtain the water. However, it does make sense over the chlorinated water.
