WESLEY CHAPEL – It is the question that appeared on social media nearly immediately after Metro Development Group announced last month its Crystal Lagoon in Epperson would be opening in the spring of 2018.Can we go, too?Everyone wanted to know if the lagoon would be open to people who don’t live in Epperson, the 2,000-home development now under construction at Curley and Overpass roads in Wesley Chapel.The answer, says Metro, is yes. With limits yet to be specified."The Lagoon at Epperson is primarily for the residents, but there will be limited guest access," Greg Singleton, president of Metro Development Group, said Tuesday via email.Exact details will be released in the coming months.PAST COVERAGE: Crystal Lagoon begins to fill. But, how much use the lagoon will get at its initial opening, possibly in February, is an unknown, Singleton acknowledged last month.Why? The lagoon water is not heated.The 7.5-acre man-made lagoon will hold 16 million gallons of purified water. It measures more than six football fields long and four-fifths of a mile around. The amenities include Caribbean-style beaches and cabanas, a water slide, entertainment plaza and an area for special events. Lagoon-goers will be able to swim, kayak, use paddle boards and sail small boats. PAST COVERAGE: View the Crystal Lagoon as it progresses. Fernando Fischmann, a real estate developer with a biochemistry background, founded Crystal Lagoons 10 years ago. He invested millions of dollars on a 20-acre lagoon along the Chilean coastline in the mid-1990s and spent five years developing the technology to keep the water clean, clear and economical.The lagoon’s patent technology uses hundreds of sensors and small injectors that add sanitizing chemicals when and where they are needed — a more efficient strategy than a pool, which depends on a higher concentration of chlorine to kill bacteria.The Crystal Lagoon at Epperson is the first built in the United States. Metro Development Group plans additional lagoons at Mirada, just south of State Road 52 in eastern Pasco; its Southshore Bay development in southern Hillsborough and in Fort Myers.
