Water Softner's salt blocks

As long as you get NaCl and not one of the mineral salt blocks, theyre fine. I've used them when I'm going away for a couple weeks and dont want Jamie to have to worry about adding heavy bags of salt to the softener. They are simply salt compressed into a block, so they take up less space than crystals - therefore I can get more into the brine tank.

MEP - they're basically 50 lb blocks of salt, typically used for salt licks for cattle. Identical to the pellets in cleanliness and content, just compressed into 1 very dense 50 lb block. I get them at the local farm supply.
 
Do they reach the proper salinity content before the next regen?
Well... good question.
What I can tell you is that I test my water every month for hardness, TDS, iron, and pH. During the times when I use blocks, hardness remained at zero so I assume the salinity was high enough.

They do dissolve slower than crystals, but I think that unless you regen a lot more often than I do for my 5 bay SS (like if you have 2 autos for example) I have to think the salinity would reach equilibrium.

Ya got me curious though, I have a salinity test kit, maybe I'll put a block in a bucket & see how quickly the salinity matches the brine tank. Heck, I got nothin else to do! :rolleyes:
 
A comment from a more authoritative source than I - www.fleckvalves.com/faq.htm

"What kind of salt do I use?
Any quality brand will work, the cleaner the better. NO rock salt or salt blocks. Pellets will work well but at times have a tendency to dissolve unevenly and will begin to form a build-up around the brine tank pick-up tube."
 
So no rock salt, no salt blocks, pellets dissolve unevenly. What the heck does that leave?

I'll probably stick with Morton "System Saver" pellets.

Ever use Solar brand pellets? It leaves a nasty brown scum in the brine tank.
 
What the heck does that leave?
Crystals. They are a little bit cheaper than pellets, a little bit less likely to form bridges. But they are a little bit dirtier, which a lot of people dont like. The ones I get have never been dirty enough for me to care.

Heres the one I get: http://www.mortonsalt.com/products/watersoftner/white-crystal-solar.html and interestingly enough they also sell a brine block: http://www.mortonsalt.com/products/watersoftner/ss_brine-blocks.html
 
I see, I thought rock salt was the same as "crystals."

As far as what Fleck says about pellets forming a build-up, I've never seen it with the Morton pellets.
 
In the past I used pellets(not morton brand, but whatever they sell at Lowe's ) A while back one of my softeners quit working. The pellets had broken down, and there was 12" of salt what looked like regular granular table salt in the bottom of my brine tank. As a result the unit was unable to regenerate properly. I then switched to "crystals". I regenerate enough that I don't have bridging problems.

I went on a dive trip to the island of Bonaire in the early 90's . If you ever have ever heard the term "desert island", that's what it is. The ocean literally meets desert. But the sea life is fantastic and European women swim topless so it's a great place to visit. They farm sea salt there. They take ocean water and pump it into giant lagoons. Evaporation leaves the salt crystals where they are raked up by machinery. There were the huge mountains of salt, probably 100-150 ft high.

The block in an interesting concept, Paul. Let us know what
