How much salt is typical a non-SWG pool?

So many variables, hard to tell. Evaporation rate, rain, etc, all play a part.

Probably a lot lower, as it is typical for puck pools to need to drain with high CYA.

Each puck adds 1.5ppm. Each gallon of bleach adds about 6ppm.

In PoolMath, go to "Effects of Adding" in the hamburger menu and play around with different quantities of liquid chlorine, granular chlorine (DiChlor and CalHypo) and pucks. The result will show how much chlorine, CYA, calcium, salt , etc. is added.

Your fill water might have some salt in. As well, muriatic acid adds a little salt.

After almost 4 years, my pool had over 3000 ppm salt while on a liquid chlorine diet. Of course, with my high evaporation rate, my CH was quite high as well.
That's all behind me now. I use softened water for the autofill and have a SWG.

Poolnovice1,

Why? Just curious why you are asking..

I get this image of some guy at the pool store telling you about the "evils" of a saltwater pool.

Thanks,

Jim R.

I'm mostly concerned about any potential damage to decking by salt.

Please explain how adding **1/35th** the salinity of seawater, to what you already have, will cause issues.

Put another way, how will going from 7.1% seawater salinity (2500 / 35000) to 10% (3500/ 35000) greatly change anything.

It's a silly argument when you think it through.

PN1,

Thanks for the feedback..

Your decking should not be effected by pool level saltwater at all.

Most bad things you hear about saltwater pools are just not true. But like many things in life, once a myth catches on fire, it is pretty hard to put it out.

I have had three saltwater pool for about 10 years now and I have had zero problems of any kind. Decking, flagstone, mechanical, corrosion, rust, etc.. Absolutely nothing.

If I was told I could not longer keep my pools as saltwater pools, I'd seriously think about filling them in..

Thanks,

Jim R.

This person says that SWGs are not good for concrete pools:

What do you guys think?

Bunk. Spreading fear. Get a K-1766 and test your salt levels, you might be surprised. I maintained a chlorine pool with liquid chlorine, after two year my salt was 2200. Typical salt for SWCG is 3200. A salt water pool is a chlorine pool, and a chlorine pool is a salt pool. Spreading fear. Ignore the fear mongering.

What do you guys think?

Salt, in concentrations that they use for deicing up north, is bad for concrete roads/sidewalks. It's so heavily salted that a half inch of residue may stay behind when the snow melts.

'Salt pools' are *zero* like that. It's read in parts per million, not millions per part.

Heck. Even at 10X the salinity of salt pools....... seawater....... every coastal bridge in the world has concrete supports laughing at the moving salt water below it.

In addition to chlorine, muriatic acid and fill water contributing to your salt level, don't forget about those pesky humans, who leave salt behind, too. It's very hard to rid your pool of them, it's thought they are attracted to the water, so there's really nothing you can do to ward them off. If it makes you feel better, you can pretend it is only their sweat they leave behind.

Speaking of feeling better, some people add salt to their non-SWG pools because they like the feel of it. Like taking a bath in soft water (sort of). Another consideration: the salinity in a typical SWG pool is less than that of human tears, but much closer than fresh water. Does that make opening your eyes in "salty" pool water less irritating to your eyes? I like to think so.
