Tonight I add salt to my non SWG above ground pool

[The Raddish]

Cleancloths, I'm not sure I understand your objections here. Many people use salt water chlorine generators to generate chlorine in their pools. They keep a salinity level around 3000ppm. Not all of that salt has been processed into chlorine at one time, so there will be salt in the pool.

Aside from the chlorine generating aspects of the equipment, I gather that the rest of the chemistry is identical to a non-SWG pool. In other words, it has no effect on the rest of the pool chemistry.

I'm shooting for roughly 1/3 to 1/2 the levels of salt for my non-SWG pool. I don't worry at all about corrosion, since everything in a pool is designed to be around chlorine. Since the reason salt is corrosive is because of the the reactance the world has to the chlorine in the salt molecules, there is no 'additional' corrosive effect from salt in the water.

As for a chemical that is not needed, as you have already pointed out, there is already salt in every chlorine pool, just at much lower levels. I don't need salt in my water, but salt in my water will make the water feel better on my skin and hair and eyes. Since my skin and hair and eyes are all important to me, adding salt to my water to make them feel better is a benefit. Since (as you have already pointed out) salt is a 'buffer' and has no adverse effects on the rest of the pool chemistry, I fail to see one single drawback of putting a modest amount of salt (approx. 1000ppm) in my pool water.

For everyone else, I'll post how much difference adding salt to the water feels after a few days of swimming in it.
