SEA Blue

Our exclusive clarifier is a food grade (nontoxic) natural emulsifier that puts the sparkle back into your hot tub water.  Cloudy water is caused by finely suspended particles that are too small to be picked up by your hot tub filter.  SEA Blue cause these fine products to attract to one another creating larger particles that can be removed by the filter system.  By doing so the water becomes crystal clear.  SEA Blue provides an overall solution to water clarity and greatly reduces the amount of sanitizer required.

Nature Pur

Nature Pur is a natural enzyme that is completely natural and harmless. These enzymes digest unsightly body oils and dead skin. Ever seen a Bathtub Ring or Hot Tub Ring? This is caused by the oils accumulating on the top water line of the hot tub.  By adding an ounce or two of Nature Pur, you will eliminate the buildup.  Oils are also a major cause in premature hot tub filter failure.  The oil will clog the filter making it ineffective.   Nature Pur attacks these oils leaving the filter free and clear to do its job.   Nature Pur greatly reduces the amount of bromine or chlorine to be added to any hot tub.


Our leading two-part liquid bromine sanitization system.  This system uses natural bromide liquid salts (same salt found in the therapeutic waters of the dead sea).  The liquid salt reacts with Oxy Pur (a MPS non chlorine shock).  The Oxy Pur breaks the salt Na Br into a pure bromine (Br) sanitizer.  Unlike other sanitization systems there are no powders or liquid binders that can create harsh odors and burn the eyes or skin.  The cycle is perpetual, once the bromine is used up it reverts to bromide salt in a continuous reaction.   The Oxy-Pur is also a very strong oxidizer that can be used with Mineral Aid as an effective shock.  It is recommended to be used safely with our mineral ionizer or ozone systems to provide a strong level of extra protection.


Our state-of-the-art alkalinity increaser is fondly called Alka-Rise. This special chemical prevents any erratic changes in the pH levels of your tub water or spa pool by providing a buffer. This special product enables the bromine and chlorine in the water to function more effectively thereby ridding the water of any germs and toxins. Our product Alka-Rise is perfectly compatible with sanitizers such as biguanide, bromine as well as chlorine.

Anti-foam defoamer

This specialty spa product called anti foam defoamer will remove all unwanted bubbles in your hot tub or spa water. Our anti foam chemical is completely compatible with all sanitizers like biguanide, bromine as well as chlorine. Sometimes the cause of bubbles can be due to phosphates which are residues of bathing suits. All you must do is squirt a tiny amount of anti-foam into the bubbles and they vanish into thin air!



Our calcium increaser is used to increase calcium levels in softer city water. It is completely dissolved in the water and you can use your spa right afterwards. Our calcium increaser is called Cal-Rise and is completely compatible with all sanitizers like biguanide, bromine as well as chlorine. Having low levels of calcium in the water can often cause metal corrosion in the spa, foaming of the water, and spoil your heater elements as well. This is where Cal-Rise comes to the rescue in making your spa last for years!


pH Balancers

pH Booster and pH Reducer is our radical pH balancers that raises or lower pH levels in your hot tub water and spa. pH Booster is completely compatible with all sanitizers like biguanide, bromine as well as chlorine. If the pH level gets too low, it can cause an acidic water to form which can cause skin irritation. Therefore, you need pH Booster.  If the level gets too high, it can lead to premature heater failure and ineffective sanitization.
