  What Our Customers Say
  "Great water, thanks for your help. Glad to get rid of my old softener. The water is no longer slippery and no sign of white build-up! The added whole house filter is nice, we are enjoying the clorine free water for drinking and in our shower." - Jim S.
  "My thanks to Randy Holloway at Clean Water Stores, Santa Cruz CA, for his unending patience with this very inquisitive customer. Although my issues in purchasing and installing my Scale Stopper 4.0 unit, and associated components may have been somewhat minor in terms of some water problems around the country, Randy continued to promptly answer my questions, and contribute to my faith that I had made the right decision in purchasing from Clean Water Stores, Inc. So far, so good, after just a few days of operation. No regrets. Thanks Randy!" - Bob A.  
  "Very much enjoying the water. Water doesn't scale up my fixtures and seems softer, but no salt or waste water like my old softener. thanks to Demian and Scott.I would recommend this product to my friends." - Susan  
  The Ultimate Water Softener Alternative

For years, water softeners have been virtually the only means of treating hard water. Other alternatives including magnets, electromagnets, RF devices and catalysts have been available but few have proven to be effective.

Technology Breakthrough
A recent development, Template Assisted Crystallization (TAC) has produced the first effective chemical-free scale prevention method. Based on TAC technology, Scale Stopper converts hardness minerals into harmless, inactive microscopic crystals.

Tested and Proven
Tested by an independent laboratory against the international protocol for scale prevention, Scale Stopper achieved a 99.6% effectiveness rating - the only technology to do so and far more effective than any other water softener alternative. Proven in over 7 years of successful use in homes and businesses.

- Complete protection from scale for boilers,water heaters and more.
- No salt, chemicals or electricity required.
- No backwash water waste.
- Long lasting media-not consumed by the reactions.
- Environmentally friendly-great fit for corporate Green programs or initiatives.

Atomic sized nucleation sites on the surface of small polymer beads convert dissolved hardness into microscopic crystals.

Once the crystals grow to a certain size they are released from the bead. The crystals in solution keep the hardness out of the water so that it can't form scale or interfere with soap.

Frequently Asked Questions

Which model or size should I get for my home?

For homes with 1 - 2 bathrooms and up to 4 persons we recommend the Scale Stopper 3.0 12 GPM system. For larger homes we recommend the Scale Stopper 4.0 or 5.0.The most popular unit is the Scale Stopper 4.0 system.

What does 3.0 Liter, 4.0 Liter, 5.0 Liter and 7.5 Liter refer to?

This is the amount or volume of the catalytic Scale Stopper filter media included. For example, the 3.0 Liter model comes with 3 liters (about 3 quarts) of the media. During operation, this media floats inside the tank and conditions the water. After about 5 or 6 years, this media is easy to dump and replace.

How often do I need to change the filter or filter media inside the Scale Stopper?

If you are on city water and choose the whole house carbon pre-filter option, you would want to change that every 6 to 12 months depending on the size of your household. The Scale Stopper media lasts for 5 years or more and is easy to change as well.

How difficult are these systems to install?

They are easy to install. Any plumber or person familiar with the most basic plumbing, can easily install these conditioners. Since there is no connection to a drain, and no electricity or power required, they are much easier to install than traditional water softeners.

How do these compare with magnets and other types of electronic water conditioners?

We have used many different types of catalytic, magnetic and electronic water conditioners over the 25+ years we have been in the water conditioning business, and these systems are by far the most powerful and effective water conditioner system we have seen. This type of no-salt waterconditioning known as Template Assisted Crystallation or TAC has been found to be the most effective by thousands of customers and independent testing. Arizona State University did an exhaustive study comparing TAC resin based systems to the electronic and found TAC to be the most effective at eliminating scale build-up. Download the Arizona State Study here. We used to use another type of similar media, called FilterSorb, but find this media is more powerful and effective in reducing scale build-up by over 98%.

How does the Scale Stopper media work?

Scale Stopper media uses a technology that produces a catalytic reaction with molecular patterns on its perfectly round high capacity surface which converts the hardness minerals of calcium and magnesium carbonate content of the water into nano crystals. The crystals stay in solution in the water, and will not build up on surfaces or in pipes, water heaters or appliances. These calcite particles are heat resistant and can no longer cause hardness deposits. The treated water coming out will also remove existing scale in your pipes. After some months, the water heater and pipes are much cleaner and free of scale deposits.

What is the main difference to softening with a standard salt-based water softener?

Water softeners use ion exchange media to remove hardness. These ion exchange resins remove calcium and magnesium ions from water and attach to the surface of the resin and replace these with sodium ions. Softening units require water for back-washing and use brine “salt water” for regeneration. The increased sodium content of the water is a concern to more and more government regulators. Water for backwashing and the salt ($200 to $400 per year to purchase salt) are an added expense.

Within the Scale Stopper system, the water hardness is transformed into microscopic crystals, but are not physically removed. These crystals cannot attach to pipes or appliances. There is no need for regeneration of the bed because the Scale Stopper system works like a catalyst (the media is not used up in the process).

Can I replace a traditional water softener system with a water conditioner and what difference in performance should I see between the two systems?

Yes, you can remove a traditional softener and replace with a conditioner system. There will be a difference with the new system in that you will not feel the slippery feeling that he had with the traditional softener. This is because the hardness was not removed but was crystallized. You will have all the other great advantages like cleaner fixtures, and pipes and water heaters free of scale build-up. The additional advantage is that you will not have increased sodium in the water. You may experience a salty taste or slight odor in the water for a short period of time after you remove your old softener if there was a lot of build-up in the pipes

This happens because the new water conditioner will clean the pipes that may have a sodium and/or calcium build up and residue in the pipes in the house from the old softener. However, this lasts only for a short time until the pipes are clean.

Will I feel and different when I shower with Scale Stopper conditioned water?

Yes. Skin and hair are softer and mineral scale will not stick to the shower doors or bath. You do not have the slipper slimy feel some report with water softeners.

Will I see any change in the laundry?

Your laundry will come out cleaner and feel softer, and the clothes will last longer.

What is the maximum operating temperature of the media?

The media will tolerate up to 140 F or 60 C.

What is the minimum operating temperature of the media?

The minimum operating temperature recommended is 38 F. The media must be kept from freezing.

What is the warranty on the tank and media?

We offer a lifetime warranty on the tank and parts, and 5 year warranty on the media!

Will the Scale-Stopper remove existing hardness scale from my pipes?

After the system is installed, existing scale will be removed from the from the plumbing for several weeks to a period of several months, eventually cleaning up the surfaces of the pipes, fixtures and appliances.

What should I expect after installing a conditioner from my dishwasher?

Dishwashers use water from the hot water side of plumbing and the temperatures can be extremely hot in the drying cycles when cleaning and drying the dishes. You may find unusual initial spotting because of the de-scaling taking place in your pipes. You also may have existing excessive scale build up in the inside of the dishwasher. The best way to eliminate the excising scale in the dishwasher is to put a cup of white vinegar in the upper basket during the washing cycle. You can also use citric acid instead of the white vinegar. This will help dissolve the existing scale in the washer arms and inside surface of the dishwasher. You may need to do this until all of the scale in the plumbing is dissolved.

It is best to reduce automatic dishwasher soap usage as much as 50% as too much dishwasher soap can cause build-up on the glasses and dishes.

Has the media been independently tested and certified?

Yes. The media has been tested by both NSF to NSF 61 and also has WQA Gold Seal. This is an independent test standard for health effects that was performed by the independent National Sanitation Foundation. The system has been tested by Arizona State University and shown to be the most effective no-salt TAC resin on the market.
