Visitors flock to the historic island town of Key West, Florida, to catch some rays, walk in author Ernest Hemingway’s steps – and to channel their inner Jack Nicklaus at the city’s crown jewel, the Key West Golf Club.

Encompassing more than 200 acres of wildlife and nature at the entrance to the island town, the Key West Golf Club beckons to players of all skills and abilities, and its Rees Jones-designed 6,500-yard Par 70 track has become a must-do when visiting the Southernmost City in the U.S.

Harchuska implemented an ultrasonic raft to aggressively treat the out-of-control growth. The solution was trialed in two of the irrigation ponds – to great success. The ultrasonic float eradicated the microcystis and kirchneriella algae, and continued, like a sentry, to zap further growth as needed.

“Though we still use copper sulfate regularly in other ponds,” said Harchuska, “the two ponds we have ultrasound in require little to no [chemicals] at all.”
