    I had a thought.

    Suppose you want to run a SWG and salt is recommended at 3000 ppm (made this up for examples sake). You add the required amount of salt and test the water to make sure you hit the PPM needed.

    Fire the unit up, and salt is converted to chlorine and returned to the pool. It eventually breaks back down to salt, and the process starts all over again.

    With the FC of say 5 ppm, if you tested the pools salt content after SWG was operational, what would the PPM of the salt be? I assume once converted to chlorine, the "chlorinized" salt wouldn't register as salt?

    If this is the case, we should be able to come up with a salt PPM recommendation that gets the good water feel without SWG.

    Looks like this is the only type of salt I can buy in bulk around here-

    Will this work? Do the pellets take longer to dissolve?

    The salt I got was pellets. They were the cleanest I could find without going to salts that have additives.

    From memory the comfort level was about 1/2 of the level for a SWG

    I'll measure mine tonight when I get home and post it here. I figure it has been diluted about 20% by rain and snow since I did it.

    Sure wish we had access to all the old forum posts.

    Good to know. These are 99.5% pure. They "melted" that fast in the skimmer, huh?

    That'd be sweet

    You and me both. We hammered this out back then. I was all set for this year, until I came back and found out the posts were poof gone...

    I've never added salt to my water. Pool was filled with city water supply. Is it safe to assume that tap water would be relatively salt free? We live in a hard water area according to Morton's website.

    Have there been any confirmations one way or the other whether salt water would have negative effects on pool equipment/structure/patio?

    IF I remember right from last years discussions, if you keep the PPM low, just enough to get the water quality benefits, then no negative effects.

    I've kept boats and fished in salt water and it will wreck havoc on anthing that is not made for salt exposure, and even stuff that is made for salt is still affected by it. You really need to think twice about that.

    If I had a concrete pool with steel re-bar I would never have gone this way just to make it feel better. Likewise if I had a heater ( I have plastic solar panels ) I would avoid it.

    Just one man's 2cents worth.

    I have a vinyl liner but a concrete deck around the pool.

    Would this prevent you from adding salt?

    I just looked at the Morton link you posted.

    They have "some stuff" added. Unknown stuff. I don't think it will be dangerous, just maybe have an affect on the other chemistry we use. I'd look elsewhere.

    I can get solar salt at a local lumberyard, but it's a few more bucks per bag. It's supposed to be straight salt, but a google search says it also has a small percentage of calcium, mangnesium and sulfate ions as this is part of the TDS in seawater.

    I'll wait and see what your readings are tomorrow before I get some and dump it in.
