10. CATION-50-BOX HI-Capacity Water Softening Resin

CATION-50-BOX HI-Capacity Water Softening Resin

Now, I am going to be throwing some hardcore science here.

Hang on till the end cause if you just read it through, I promise you will get it.

This is a cation resin made from conventional gel polystyrene designed for ion exchange to result in water softening.


Now, what does that mean?

Well, but it is a raw free ion, which will mix with the already present free ions in the hard water.

It can be used for both residential & commercial purposes.

The sodium cation removes the free mineral ions such as calcium and magnesium, thus eliminating the hardness of your water.

The standard mesh cation exchange resin is one of the most economical water softening products.

If you are going a little tight on budget, you may give it a shot.

Its effectiveness is no less than a traditional sodium salt water softener.

If you stay in an area where the water is excessively hard, this is your best bet.

After the cation resins get exhausted, there is regeneration by adding concentrated sodium or potassium chloride solution.

Pros & Benefits:

  • Highly economical water softening solution
  • Regeneration of resin beads after saturation
  • Works for both residential & commercial purposes

Some Extra Info

As much as hard water sounds like an oxymoron, an overwhelming 85% of the USA has hard water issues.

The best way to check if your water is hard or not is to see if there is a film of residue or a foamy lather while washing your hands with soap.

The latter suggests soft water.

Scientifically speaking, hard water is said to be the one in which there are excess mineral ions like calcium, magnesium, etc.

So, is hard water too bad?

How will you know how hard your water is?

And can you keep on using it?

Well, to begin with, scientifically proven in some cases, it is even advised that people are going low on minerals to drinking hard water.

So, no, it’s not disease-causing, but if the concentration of minerals increases and you throw in some free iron ions, arsenic, or organic compounds, it may sure be a threat to your health in the long run.

Water hardness is generally measured in grains per gallon.

Anything above121 mg/L is said to be hard water.

To confirm the degree of hardness of water, you may purchase a water test kit or contact the local authority to come and test it for your home.

Depending on the results, you may decide whether to use a water softening system.

Some Things You May Do To Maintain Your Water Softening System

  • Maintain Salt Level

This is very important as failing to check hard water regularly may result in you getting hard water.

So, the thumb rule is to check the salt levels in the tank every 4-6 weeks.

However, this frequency may change depending on the water consumption of your home.

  • Clean The Brine Tank

This is the place where your user manual would come in handy because every system needs a different frequency of cleaning.

Although the present-day brine tanks don’t necessarily need regular cleaning, it depends on the model.

I suggest that you should do a cleanup before trouble arises.

  • Removing The Salt Bridges

You may observe that your water softening system develops salt bridges after some time.

This is caused either due to using deficient quality salts or high temperature & humidity.

These bridges clog the resin beds and hence disable the water softener to work correctly.

To keep it working smoothly, ensure that the decks are cleaned properly to avoid any damage to the softener walls.

  • Clean The Resin Beds

The resin beds are filled with salts but cleaning them once in a while, maintains their efficiency.

Due to the presence of iron and heavy metals, these resins sometimes do not function properly.

Hence, you may want to flush them with clean water for better results.

  • Using The Right Salt

I cannot emphasize this point enough that the salt that you put into your softener determines its longevity.

Read the manual to understand whether cubes or crystals or pellets would be best suited for your system.

Also, follow the right way to insert the salt.

And obviously, know the intent of water softening your home or industry.

Each use requires a different kind of water softener salt.

Final Thoughts

Now that you know all about the best water softener salt in the market, the best way to decide which one to go for is to understand your intended personal use.

The factors that are most important for you will determine the kind of salt you purchase.

Also, you must know the water consumption of your household.

And don’t forget to check the compatibility of your water softening system.

If everything clicks, only then is it going to pay off in the long run.

Although it’s not proven yet if they ultimately outweigh the benefits of sodium-based salts, if you are sure about cutting down your sodium intake, then you might go for potassium salts.

And yes, there are systems other than water softening salts to remove your hard water problems, but well, each of those techniques has their positives & negatives.
