Dive Rite in Hot Tub Salt and Spa Salt for All Salt Water Systems Including Hotspring, Jacuzzi, Caldera, and Chloromatic - 4 Pounds

They dissolve very well given you follow the instructions which aren't difficult. It's just throw some in and don't let it all clump at the bottom. It feels great, it's refreshing, the bag has a lot in it. It's a good value. I like this.

Overall, I do like this salt. I did find the bits to be a bit larger than I am use to. Though they did dissolve it did take it longer due to the size. I normally let my hot tub run 20 before retesting but I ran it for a good 40 minutes to ensure it was dissolved well

I got this more for softening the water in the hottub more than sanitation. Easy to mix in a bucket of warm water and pour into the tub. Dissolve fairly quickly but there's always a few salt grains that take a little longer to dissolve. Functions exactly how it's supposed to. Makes the water quality soft and feels great on the skin. A little expensive for the size bag you get since it's just sodium chloride. But if your not using for water sanitation then it goes a long way.

I know what this may look like but it’s just salt. The salt on the left is the Dive Rite Spa Salt and the one on the right is the current brand I use. You can visibly see the difference as this spa salt is indeed more coarse. It still dissolves just not as fast so technically it does get the job done. I will be curious to see how it does over time since it is more coarse, but all in all it does what it needs to do.

This is for spas and salt pools as a chlorine substitute. It's not suitable for foot soaks and such

I’m really pleased with the Dive Rite Hot Tub Salt and Spa Salt. The salt has a great consistency and dissolves quickly without any residue, which makes it super convenient to use in my hot tub. It effectively balanced the salt levels, and I haven’t had any issues with my system since I started using it. The quality seems excellent, and it’s straightforward to use. Overall, I’d highly recommend it for anyone maintaining a saltwater spa system.

This is simple, 99% sodium chloride and seems to be of a good quality. The issue is that the price, ~$13 for just 4 lbs, seems very high. I will update this review if needed based on further experience.

Large grains of salt that dissolve completely. No noticeable residue or other debris left behind. Adjusted to proper salt % with no problems. Overall it's a good quality salt just seems a little on the high priced spectrum.
