Seems that the scripps water is good enough even after a rain for me and with the price of salt being rediculas I really don't have a choice but to use it. I drive a 4by4 chevy that is'nt too good with gas but only live a few miles away form scripps so the gas versis the price of salt isn't even close for me. And with the 90 gallons I pick up at a time and use each month the cost of salt would break the bank using that much water.
