Changing to salt filter
We have an above ground metal pool. It was not purchased at Walmart. It is 4and 1/2 feet deep. 15,000 gallons of water. We were needing details on how to switch it over. It has a sand filter. We were concerned with it maybe rusting? Is this an issue? I feel salt will save us money over time as chlorine and bleach has gotten expensive and salt might be better for our skin. Any help on this is appreciated. Thanks so much.

Re: Changing to salt filter
Just fit the SWCG
The salt won't be as strong as sea salt
You really need one twice the rated output for your pool because the are based on 24/7
The cells do wear out though and can be expensive

Re: Changing to salt filter
The metal usually used is a zintec type so quite rust resistant. The std salt chlorinators use around 3500 ppm of salt, the sea is around 35000 ppm. There are low salt versions that use around 1500ppm and that is below most corrosion level. You need to start with stabilised pool salt to get the right CYA level 30-50 ppm usually but often up to 70ppm with chlorinators.
Low salt chlorinators are a bit more advanced and produce hydroxyl radicals as well which are far more powerful than chlorine. The chlorine is only there as a residual with the hydroxyl radical doing most of the work. Look at AOP water treatment, Advanced oxidation process. Do also check your pump can use salt water not all can.

I may not give you the answer you want to hear, but I will give an honest opinion of your situation as you decribe it.
