Eco-Matic opened in Japan in 1976. They've now come to Southern California, what might be known as the "swimming pool capital of the world." And that's perfect for the company, which sells pool water purification chemicals and equipment. They work with both residential and commercial clients, the latter of which work with Saltline USA, Eco-Matic's commercial division. EcoMatic filtration and cleaning systems depend on salt water to effectively keep your pool clean and clear.
