Tonight I add salt to my non SWG above ground pool

[PatL34]

In the 8 years that I have been using a SWCG, I have never had any problems with corrosion from salt, from any equipment at all.

My wife who was a pediatric nurse, appreciates the "silky" feel that salt can give, no itchy eyes, no scaling on the skin.

John, with all due respect, you do not take your car for a swim in your pool, but you are fully prepared to drive it on salty roads, knowing that you will have corrosion if you do not wash the undersides with fresh water. Been there, done that.

Seawater has a concentration of 3% salt, whereas a pool has 3,000/1,000,000* 100 = 0.3%. This is apples and oranges.

If you have to talk corrosion, then aluminum, copper, carbon steel, iron, brass are the metals you have to worry about. On a boat at sea, you had to have zinc anodes to reduce the corrosion on other metals.

The only areas that salt will give a problem is with a concrete border next to the pool, and aluminum rakes. Beyond that there should be no other effects.

Hope this helps.
