    Salt type?

    I found a great deal on Red-Out. Can Diamond Crystal® Red·Out® Pellets with Iron Fighter® Formula be used in place of Diamond Crystal Solar Salt? Thanks

    Re: Salt type?

    I wouldn't use either one, really. The pellets are too big, IMO, and take too long to dissolve.
    I would absolutely not use the red out. I checked the MSDS for the product and it contains citric acid as well as a metal sequesterant that's a phosphate derivative. Both of these have their uses to control metals in pools, but they should be used in the proper way and amounts. Salt added for salt water chlorine generation should be free from any additives. Just use plain old sodium chloride with no additives.

    Re: Salt type?

    to clarify, the plain solar salt is fine for pool use; it is a large crystal.
    Any water softener salt pellets that are >99.5% pure are ok, too, they just take longer to dissolve. Brushing speeds the process.

    You do not want rust inhibiter or iron fighter. Salt with those "features" contain an additive that will cause stains. Pellets are not preferred, as they take longer to dissolve, but they will work. If using pellets you will probably want to do a little extra brushing just to make sure they completely dissolve.

    It's actually the anti-cake ingedients in some salt that can cause the staining. The citric acid and sequesterant in the red out wont stain, its just not a good thing to add with the salt.

    I typically use Diamond Crystal® Extra Coarse Solar Salt and it seems to disolve pretty easy. What brand of salt does most of you use?

    Morton pool salt, usually. I get it at Lowes.

    Re: Salt type?

    ARe there really any benefits of using Dead Sea or Himalayan salt over Mortons/pure water softener salt? Is this just marketing hype as it costs 31x as much! Thansk!

    Welcome to the forum

    I think the only benefit would be impressing your friends... "Hey, this isn't just any salt, you know... It's imported!"

    Re: Salt type?

    Lets make this clear.

    99.5% or purer Sodium Chloride with no additives.. It doesn't matter if its gems, granular or rocks. Granular is the fastest to dissolve, The others require more brushing. All Sodium Chloride salt, regardless of whether it is in a Morton's, Diamond Crystal, or generic is salt. Some come in 40 lb bags, some in 50, some in 80, ahh, you get the point.
