I am curious about the actual concerns of running a salt water system with an above ground pool that is not designed for use with salt water. I am very well aware of the risks of increased corrosion and all, but what is the real world risk? My pool is 4 years old, and looks to be in good shape with no leaks. I am not really concerned if the pool lasts for 30 years, so if I get another 4 years out of it and don't have to worry about tabs or chlorine jugs, then it is worth it to me. So whats the realistic impact of pool life when running a salt water system on my AGP?
