What Is Dura-Cube Salt? Everything You Need to Know

From the outside, all water is seemingly the same – clear, mostly flavorless, with two hydrogens and one oxygen. But once you get past the basics, water is actually very versatile. It can be distilled, filtered, tap, and (if you’re really fancy) there is water marketed as kosher, organic, or kabbalah. Water can also be hard or soft. Dura-Cube Salt

High concentrations of minerals make water hard. Both soft and hard water is generally safe to cook, drink and bathe, but hard water can lead to different side effects. Research shows consuming hard water is related lead to potential health risks like cardiovascular disease, dermatitis, and kidney stones.

Most cities and states do soften the water supply by removing minerals like calcium and magnesium. However, many a time, the water you get in your household is hard water. So, how do you treat hard water? The answer is simple: Using a water softener. Adding the right water softening salt to your brine tank will improve its efficiency.

Today, we will talk about Dura-Cube salt, one of the most popular water softening products out there.

So, let’s dig right in!

What Is Dura-Cube Salt?

Dura-Cube salt is not just another ordinary salt. It has been known as the best water softener in the world for years. It is 99.98% pure sodium chloride salt that helps you soften water and reduce the number of dissolved solids.

There is also a potassium chloride variant available as a low sodium alternative. Dura-Cube salt will help you remove magnesium, calcium, and sulfur minerals regardless of which one you choose. The strength of this salt is ideal for use in both open-and closed-loop water softeners.

How Is Dura-Cube Salt Different Than Standard Salt (Sodium Chloride)?

The difference between Dura-Cube and common salt (sodium chloride) is that Dura-Cube has a specially formulated additive that bonds with hardness minerals. This accelerated bonding period provides softened, clear water that is more manageable in the long run.

The main ingredient in the Dura-Cube Water Softener System is Potassium Chloride (KCL). Such additives aid in the reduction of hardness minerals, calcium, and magnesium. It is an excellent alternative to sodium chloride.

The other active ingredient in a water softener is sodium chloride (NaCl). This is also a salt used to regenerate your water softener. Sodium chloride can be found in most grocery stores and home improvement stores.

It is important to note that sodium chloride tends to be more corrosive to your appliances than KCl. It also contains calcium, magnesium, and sulfur, all minerals that hard water contains.

How Does Dura-Cube Salt Work?

Direct contact with hard water minerals can cause staining on your clothing, dishes, and kitchen appliances. Dura-Cube salt will help remove hard water mineral stains from your laundry and reduce scale buildup on fixtures and appliances.

When potassium chloride (KCL) salt dissolves, a positive charge is left behind. This positive charge attracts and binds to calcium and magnesium in your hard water, reducing excess mineral buildup.

When these minerals are removed, many damaging effects are eliminated or prevented from occurring in your household, including white ring buildup on fixtures and scratch marks on dishes and glassware.

Who Makes Dura-Cube Salt?

Dura-Cube salt is made by Cargill Salt, a USA-based company dedicated to providing the best potassium chloride available. They use 99.8% pure KCL in their formula without any anti-caking or other additives.

The result is an enhanced salt delivery system with accelerated hardness binding and removal abilities that keeps your water softener running at maximum efficiency for many years.

It has been found that potassium chloride is better for the environment than sodium chloride (NaCl) due to the lower amount of sodium added during its production process.

Does It Matter What Salt I Use In Water Softener?

The Salt in your water softener is what does most of the work of cleaning and regenerating your system. Most water softening systems on the market use salt to soften their water. Standard sodium chloride performs this task reasonably well, but potassium chloride (KCl) is a better option for several reasons.

The first reason is that it bonds with minerals quicker and more effectively than sodium chloride, which means you will get clean water sooner. This can be especially helpful if you have hard water with high levels of iron or sulfur because the quicker bond will allow your system to regenerate faster so you can enjoy purer water sooner.

The second reason is that it is less corrosive to your appliances, which can also be vital if you have a water softener that uses stainless steel or chrome to regenerate.

What Is The Best Type Of Salt To Use In A Water Softener?

The salt in your water softener is vital as it determines how well it will work to clean and regenerate your water softener. It has been found that potassium chloride is better for the environment than sodium chloride (NaCl) due to the lower amount of sodium added during its production process.

A study by the University of Arizona Agricultural Experiment Station showed that potassium chloride is better for the environment and does not leave harmful residue in the soil.

The most common type of salt used for water softeners is Potassium Chloride. It is better than sodium chloride as it effectively removes contaminants from your drinking water supply and leaves behind fluoride. Whether you use tablets, pellets, or a brine tank, it’s worth looking at our potassium chloride alternative.

Where To Buy Dura-Cube Salt?

It is not always easy to find where to buy Dura-Cube salt. Only a few select stores carry our professional-grade water softening salts. You can find Dura-Cube potassium chloride salt at hardware stores and other grocery stores.

You may also find them in online stores. You can purchase Dura-Cube in a variety of different-sized bags or individually by the pound.

How Much Dura-Cube Salt Will I Use?

You may need to test your water before determining how much Dura-Cube Salt you will need. Each softener and the amount of salt used are unique to every customer.

The higher the hardness of your water, the more particles need to be removed from your supply line or pipes, causing a higher salt consumption rate.

Is It Safe To Use Potassium Chloride?

Dura-Cube Salt

Potassium Chloride is a proven regeneration aid as it reduces the amount of calcium and magnesium in your water. Potassium Chloride is considered one of the safest softening options available today.

It has been proven to not cause any adverse effects on the environment. In many areas of the country, potassium chloride is required by law to be used with water softener systems.
