The Clear Choice

Start enjoying your swimming pool

... We’ve been adding copper and silver to swimming pools around the world since 1982 with a goal of making every Caribbean Clear pool look pristine while reducing cost, chemicals and effort. Who else can claim that? Protection from harmful pathogens including troubling algae means less worry and more time for enjoyment. Take the plunge and experience why the most common question from Caribbean Clear owners is: ”Its so great, why doesn’t everyone have one?”

A truly smart technology that DOESN"T require a complicated installation, programming, daily attention, backup batteries, reset after power outages, bluetooth, or a cell phone. Once calibrated to your pool’s needs, simply confirm proper level periodically along with your regular pool tests.

How It Works

Simply two metals

In nature, 2 metal elements often go unappreciated for their surprising ability to purify water. Long before man understood science, he noticed coincidences. The zodiac could be used to time the warmer and colder seasons, copper containers prevented water from turning green, and those that could afford true "silverware", had fewer health issues. Man had stumbled on an all-natural mineral pure water technology.

Copper is the most powerful natural algaecide on the planet. It is used in ponds, reservoirs, and by water treatment plants. While early pools benefited too, copper was largely forgotten as chlorine quickly became a cure-all, when it was learned that enough chlorine could destroy just about anything.

... Silver had proven its ability to control pathogens throughout medical history long before NASA saw it as an opportunity to safely, non-toxically, and non-corrosively purify recycled water aboard APOLLO space craft.

Offering the longest lasting residual of any water treatment method means the hottest summers, periods of non-use, or even winterization will not reduce its effectiveness. Spring startup can even be easier.

Caribbean clear became a pioneer in water treatment in 1982 when it combined NASA's ionization silver delivery technology with copper in a scientifically proven ratio suited for the needs of addressing swimming pool water.

Custom engineered electrodes are unique to Caribbean Clear, both in their 93% copper and 7% silver ratio and their design which has been cast in a specific shape to insure optimum wear, life, and ease of cleaning or replacement when necessary. These are not simply made from "off the shelf" 99.9% copper alloy rods or extrusions which contains less than 0.05% oxygen and even less silver.

Adding Caribbean Clear to your pool

Something Here


Sufficient, consistent and user adjustable copper and silver addition are necessary. You might own an indoor Jacuzzi, or manage a multimillion gallon swimming complex. It might be a quiet pool for the family or maybe the neighborhood kids hang out there. Whether you swim in Alaska, Florida, or near the equator, sizing the right Caribbean Clear system to your application and unique plumbing or wiring and voltage requirements is necessary to ensure your satisfaction. Don’t be fooled by products claiming, “one size fits all” and advertising fine print stating that 2 or more systems may be required. Our systems will be properly sized and unlike non-powered cartridges that rely solely on the pool water being corrosive enough to dissolve copper foil (let’s hope it’s not), Caribbean Clear forces copper and silver into the water by a user adjustable constant current source, providing that “just right” level while automatically compensating for electrode wear, fouling and changes in water conductivity.

Converting to Caribbean Clear, regardless of your current method of purification, is easy. An electrode chamber is plumbed into an available location and power is tapped from the existing circuit controlling your pump. You can even keep or continue to use any current method of purification if you wish, with the rare exception of chemical Biguanides.

Safe and Effective

Engineered from the ground up for electrical safety.

Look for the UL AND NSF marks on our products, which attest to our commitment to your family’s health. Health departments widely respect these agency’s testing protocols, unannounced product inspections, labeling requirements, and allow many of our products to be installed in commercial pools. Our recommended levels of copper and silver meet the EPA standards for drinking water.

Don't let other treatment products ambiguous or uniquely worded UL or NSF statements lull you into thinking a product is safe or has even been tested to a recognized standard by a reputable company. For example, UL listed wall chargers were never tested by UL to provide the necessary electrical isolation and safety for swimming pool equipment. Our transformers follow UL’s most stringent requirements for electrical isolation and are 100% high voltage insulation tested both as raw parts and in finished Caribbean Clear systems. If you want a solid product with an extensive safety history and proven to do what it claims, then you want the Caribbean Clear brand by name.

Reduce maintenance costs

This eco-smart technology doesn’t mean more expense.

From the moment you install Caribbean Clear and cut back on chlorine usage, the life expectancy of everything associated with your pool will be extended. Imagine fewer trips to the pool store too. All this while using less power than an average table lamp.

Extended Product Life is assured through rigorous component selection and a week long testing and burn-in period. Everything about our popular systems from the metal enclosure to our custom cast 93% copper and 7% silver electrodes, is custom engineered for safety, efficiency, longevity, performance, and backed by our 10 year limited warranty.

Forget buying algaecides. With Caribbean Clear protecting your pool, you have the best algaecide and in its most concentrated form. Chlorine reduction means less pH correction. Consider that most chemicals starting with chlorine and going down that dreaded shopping list from there, all affect your pool’s chemistry, often fighting with each other. Reducing some while eliminating others means less affect on your, wallet, pool and maybe even the health of those in contact with the water or breathing the air just above the water line.

0.4 not 4.0 While most pool owners struggle to maintain water quality with 1.0 to 4.0 ppm chlorine, and many use more, with Caribbean Clear installed, a barely detectable 0.4 ppm chlorine level is recommended as part of the NSF standard for copper/silver ionization. Ionization is not a cure all, and some added oxidation is still needed for that sparkle we all desire.

Caribbean Clear vs. the other Treatment Methods

... Recent years have seen a renewed surge in the promotion of these systems. Thirty plus years ago, they were lauded as the treatment method of the future (no they are not a “new” technology). They then faded into obscurity. Electrical expense, electrode costs, damaged concrete, staining, and corrosion were some of the side effects that couldn’t be overcome. Today’s systems are no different. Pool owners and builders are still learning or painfully remembering that salt laden water, even splashed from pools, causes equipment, structural, and concrete damage just as it does roads and cars in the colder climates that use salt as a method of de-icing in winter. According to the December 25th, 2006 issue of “Pool and Spa News”, pool builders are seeing pool damage starting in as little as a few weeks. Flaking of coping, decks, and equipment warranty issues stopped some builders from promoting these systems. Some are requiring signed disclaimers when pool owners specifically request a salt system. "Salt basically gets into everything nice and ruins it, even auto-covers.", per a Custom Pool Builder in MO.

Advertising leads you to believe that you simply add salt. Even “The Association of Pool & Spa Professionals” recently contributed to an “Associated Press” article on current pool trends where they state: “Chlorine alternatives: Salt does a good job of keeping water clean and preventing algae and costs considerably less than standard chlorine treatments.”

Salt alone doesn’t keep water clear and free of algae. Ocean life depends on algae. Chlorine generators simply generate chlorine gas and hydrogen gas from salt and water at the expense of your power bill. Once mixed with pool water, chlorine gas produces the exact same active sanitizer as the chemical chlorine you are currently using. This chlorine will continue to burn eyes, dry skin, and bleach bathing suits. Chlorine generated from salt is not a chlorine alternative, just as choosing to fill the pool with buckets instead using a hose is a water alternative. In the end, neither the chlorine nor water are different regardless of the method of introduction.

Unlike traditional chlorine usage, chlorine generators must have safeguards in place to assure that the poisonous chlorine gas they generate does not escape from the pool or its plumbing or that the explosive hydrogen gas formed at the other electrode is not ignited. Either can happen when the water stops flowing. Many manufacturers rely on nothing more than a $5 pressure switch for this safeguard while others assume that loss of prime, broken impellers, plugged leaf baskets and other failures which stop water movement won’t ever happen.

Although recommendations of salt addition vary based on electrode size and power requirements, one advertisement states that as little as 1 teaspoon per gallon is needed, which doesn’t sound like much until you consider 15 or 30 THOUSAND teaspoons. 150, 300, or even 500 pounds of salt might just explain the "silky" soft-water feeling many advertise. Pool builders have always discouraged filling pools with “softened” water due to pool surface problems. Don’t expect to use inexpensive rock salt either, as it contains an anti-caking agent called “yellow prussiate of soda” which contains iron, which can lead to unsightly yellow stains and you may also notice a rather unpleasant term associated with its actual chemicals name… “sodium ferrocyanide” which might explain why it can’t be used in saltwater aquariums either.

... There is little doubt that germicidal UV radiation (UVC) is effective in killing microorganisms. Upon learning that UV light leaves behind no lingering chemicals or byproducts, you might easily be convinced that UV is the perfect sanitizer for pools. But further investigation will show that UV light has a dark side. Lurking in the shadows of this powerful radiation source, we find algae and bacteria flourishing. There is no effect on what the "light" doesn't reach, so only the water that passes by the light source can be purified. Glass, air, dust, particulate matter and even water, reduces or prevents transmission of germicidal UV radiation. To make matters worse, UV doesn't have any residual, so the second the water heads back to the pool or your pump turns off to save electricity, algae and bacteria are free to grow. UV manufactures even state that UV is more effective at low flow rates, ie less circulation. In fact, algae and bacteria will be a constant problem for any areas of the pool that do not get good circulation and the pool walls will soon be full of clinging algae and bacteria.

Another often-overlooked aspect of UV is its interaction with chlorine. Assuming that you are doing everything correctly, using a properly sized UV source, and maintaining a suitable chlorine level, you will find that you are not saving as much as expected. You may even be using more chlorine. What could be the problem? Where is the chlorine going? Look no further than those hot summer days where the chlorine just seemed to magically disappear from the pool. Maybe this was even the reason you begin investigating alternative methods of purification in the first place. Congratulations, you have just come full circle. Natural UV radiation was responsible for degrading your chlorine, before you bought a UV system and now you are paying to degrade it faster.

... Ozone is a great oxidizer, and it does a good job of destroying algae and bacteria. Its residual effect is best described by the term “half life.” You may remember this term from chemistry class while studying nuclear radiation. This is the time necessary for “half” of the compound to break down on its own and become ineffective. Unfortunately for ozone this is about 15 minutes. The moment the water exits the ozone chamber the clock starts and 15 minutes later only half of the ozone is present. At 30 minutes one quarter is present. At 45 minutes only an eighth of the original ozone level is present. Imagine trying to keep up with chlorine if a 2.0 ppm level was unreadable less than an hour later. So it goes with Ozone. Actually 15 minutes is rather generous considering that half life diminishes as temperatures increase. Even NSF International, the primary standards and testing agency in the US for swimming pool products and treatments states, “It is very difficult to maintain a measurable ozone residual in pool water” and mandates the need for typical chlorine levels even when ozone is used.

Ozone is not very soluble in water and, like air bubbles, it would rather float to the surface. Being heaver than air it concentrates at the water’s surface where swimmers breathe. Ozone is a powerful pollutant, often referred to on the summer evening news, so it is no surprise that OSHA has set the short-term exposure limit at only 0.3 ppm.
