There is one potential problem I see for salt added to an above ground pool.
And I believe someone else has mentioned it on at least one other thread.
When salt water splashes over the wall, it flows down into the lower track. where it will evaporate and form salt crystals. I am not sure how corrosion resistant the track on an average AG pool is, and what effect there might be.
This is the one factor that has been keeping me from adding salt to my AG.
Thoughts ? Opinions?
.
My opinion on that is that this is such a small amount of salt that it really won't matter. There is already chlorine in the pool. The bottom track is designed to be protected against chlorine. The reason salt is corrosive is because of the chlorine in the salt molecule.
If we were talking about raising the salt content in our pool water to 20,000ppm or more (to the salinity levels in ocean water), then I too would be concerned about corrosion. But we're talking about 1200 - 1500ppm, which is half or less than the 3000 - 3700ppm that recommended by most SWGs.
I haven't found any corrosion warnings associated with any SWGs.
I think that at the levels we are talking about here, there are no drawbacks at all, only benefits.
Oh, and I purchased another bag of salt to put in the water this evening.
If it is aluminum, it can corrode. Some AG pool vendors may not guarantee the warranty, if you use a SWCG. You may want to check this.
For inground plaster pools with a concrete border make sure to wash any salt spilt on the concrete into the pool with a garden hose.
Hope this helps.

I really can't wait to do this. But I need to get a handle on BBB first.
We have a whole house water conditioner system which uses that salt, and it makes a huge difference in the house, so I'm sold on it being useful in the pool. I'll probably target the very low end so I don't have to worry about the possible corrosion issue. It sounds like even at 800ppm, there's some tangible benefit.
Mom2Czars, you can do this independently of the BBB system, as it will not have any effect on the rest of your pool chemistry. If you want salt in your pool , just put it there.
I have a 8500 gallon in ground fiberglass pool and I want to add salt.
Here's my question: since I have a problem with iron stains would it be ok to get this kind of salt:

The thing I don't understand.. they all say pure salt so how can they be iron fighting, etc. ?
This may sound strange but I work in a hospital and the main ingredient in IV's for sick people is normal saline which is salt. I know there is some complicated chemistry going on here, but if its ok for us to have a certin amount inside our bodies, whouldn't it be ok to have it outside too, as in our pools?
In a word: yes.Originally Posted by Kimrst

The pH of the .9% sodium chloride IV solution ranges from 4.5-7.0 (it states this on the bag). Anything under 7.0 is too acidic for the vinyl and can destroy it. Therefore it is not a safe assumption to state that if we put it into our bodies we can put it into the pool.
I do however like the idea of adding salt to the water. I plan on doing this in a few weeks when I am through with this treatment.
