Seawater instead of salt
Someone has w-a-y too much time on his hands - LOL.

If possible, it is actually a better idea to fill the pool with seawater rather than dumping 600lbs of salt. The chlorinator will work to bring the salinity/PH to normal levels. The advandage of seawater is the rich minerals it has. Use a UV filter to kill all bacteria and... enjoy!
I am working on a prototype (seawater pump) powered by ocean waves to provide constant supply of seawater to the pool while draining the "old water" via the skimmers overflow.
Reason = eliminate pool pump, chemicals and associated filters. Seawater health benefits too many to mention but without the jellyfish, sharks, ocean pollution etc.
Seawater pools are becoming very popular in Greeece, Cyprus and other mediterranian countries. Thalassotherapy is a natural health practice (google it).
