I keep sacrificial anodes on my ladder and one in the skimmer and one by the equipment and have to replace them every few years from being eaten up. There is no doubting that salt eats metal, you have to give it something to eat other than your equipment.
We started with passive anodes. Two on the ladder and a 2" x 4" one in the skimmer. Last year I think it was we added the in line. Having a steel walled pool and seeing the ones on the ladder and skimmer being eaten up spooked me. Also my ladder hinges (we have an auto cover so ladder must fold up) and stainless steel ladder all have rusted.
22,500 gallons of water takes 68oz of 8.25% bleach everyday to raise FC by 2. (Thats about what the average person uses)
So every day, 68oz of bleach adds 3.3 ppm of salt.
Open all year long? = 1204 ppm salt a year.
Open 9 months a year? = 903 ppm salt a year.
Open 6 months a year? = 600 ppm salt a year.
Open 4 months a year? = 396 ppm salt a year.
This is without shocking and dilution from rain water.
