Costco salt - Culligan brand

[jetranger]

Hi all, I've read numerous threads on salt brands and have figured out it really doesn't matter as long as it's pure.

I saw this Culligan salt at Costco. It's pretty inexpensive. It does have something called Sofner-Guard. I didn't see any info on Culligan website and there is non on the bag.

What do you think? Safe to use? This is my first time with SWG, so I'll be adding about 8 bags.

Thanks!

"Advanced Cleaning Formula" - probably some type of resin cleaner. I wouldn't use it in my pool.
Look for solar salt at Lowes, HD, etc. The Diamond Crystals brand of solar salt is what I use in my pool - blue bag, not yellow. 40# for under $8 in AZ.

Good price though - I'll have to see if they carry it at their AZ stores and use it in my water softener.

The "Sofner-Gard II"[sic] "Advanced Cleaning Formula" would make me nervous -- that could be some additive you won't want in your pool. For a one-time $15-$16 total difference I probably wouldn't risk it.

Note that a few people have had issues with Morton's salt lately (dirt and rocks that stained their pools at least temporarily), so I might also avoid for now. I have used the Diamond Crystals brand myself recently and it's appeared to be pretty pure.

This is a standard softener salt pellets sold by Costco. In my area they sell the Diamond Crystal brand.

Everyone is super cautious, but reading the MSDS of the Diamond Crystal brand of pellets... I think I'm sold. It seems even more pure than the blue bags! And the 0.03% of SHMP doesn't seem like an issue at all. I plan to dissolve in warm water in buckets before pouring into pool.
