The "Natural Solution" for pools and spas What is ECO-MATIC? How does it work? ECO-MATIC is a proven alternative to the use of commercial sanitizing/oxidizing chemicals in pools and spas. There are 3 components to ECO-MATIC - two product components are easily attached to your existing pool filter equipment. The third component is pure water - creating a very mild salt water solution. PURE, NATURAL PROCESS.... As the mild salt water passes through the in-line ECO-MATIC "Cell" electrolysis converts a portion of the dissolved salt into pure, effective sanitizer (the same effective sanitizer, in part, as would result if chlorine was added to the water - but without the potentially dangerous chlorine compounds and the obnoxious "chemical" effects commonly associated with manual chlorination - and without the need to handle chemicals. The sanitizer produced by ECO-MATIC will keep your pool water safe, healthy and crystal clear, by oxidizing (killing) any unwanted bacteria, virus and algae which may be present in the water, This automatic process does not consume the salt, but simply re-cycles it, over and over again. ENVIRONMENTALLY POSITIVE ECO-MATIC is the most environmentally positive swimming pool product available today. Re-cycling a natural product (salt) can never be harmful to our environment.
