Salt chlorination is the best option. You have to ask for the pool not to be salt in Australia.
Takes the guess work out of proper sanitation. The electrolosis splits clorine gas of the salt and it runs through the water to create liquid chlorine (Sodium hypochlorite) The (<removed>) salt levels need to be kept at 4,000 ppm (Sea water is around 55,000 ppm) Plus the salt softens the water giving a better bather experience.
I would stay away from both companies mentioned and definately liner pools.
