Sigma Pool Systems The Sigma III Pool/Spa Ionic Purifier The Sigma III Pool Conditioner Sigma Pool Systems Commercial/Municipal Applications With the Sigma III Pool System in your pool or hot tub, you will be able to enjoy hours of fun without all of the skin irritations, red eyes and nasty odors. The Sigma III releases very small amounts of Copper and Silver into your water electronically. Copper kills algae and prevents its growth. In fact, many chemical algaecides that are added to chlorine pools for the purpose of algae control, are Copper based. Silver, on the other hand, kills bacteria and also prevents its growth. By using these two natural elements, you are able to accomplish the same job as chlorine, but without the harmful side effects. And, it is perfectly safe to use copper and silver in these small amounts. Why Should I Use The Sigma III? The Sigma III provides quality pool water that is virtually odorless and chemical free. The Sigma III eliminates the need for chlorine. Chlorine, a dangerous and toxic chemical is known to cause eye and skin irritation, bad odors, hair damage, damage to swim suits and to the pool and related equipment, while at the same time being ineffective in its primary function. Some forms of bacteria, such as that which causes "Swimmer’s Ear", are not readily effected by chlorine. Chlorine and its by-products have also been shown to contribute to heart disease, cancer and other degenerative diseases. The Sigma III eliminates the need for chemical algaecides by controlling algae and fungus non-chemically. The Sigma III eliminates the need to store dangerous and toxic chemicals. The Sigma III eliminates the need to periodically shock the pool by super-chlorination to remove inactive chlorine and other compounds (chlorinated organics). The Sigma III saves money. The Sigma III eliminates the ongoing and never ending expense of chlorine maintenance along with the expenses for algaecides, shock and maintenance charges. The Sigma III eliminates use of cyanuric acid, a cyanide derivative as a water conditioner and stabilizer. As usage of such conditioners cause a buildup of cyanide in the pool. It then becomes necessary to drain and replace the water. The Sigma III reduces the amount of wear and tear of filters, pumps, heating and cleaning system parts by eliminating corrosive agents such as chlorine and especially shock (super-chlorination) treatment. The Sigma III comes with a full 5 year warranty and free lifetime refills for the reagents used in the SIGMA III Copper Test Kit.   The Sigma System The Sigma III Pool/Spa Purification system is made up of three main parts: The Control Box The Flow Cell Electrodes See how this is installed into your existing pool pump system.
