Every great pool has a something that gets visitors to stop in their tracks and take a closer look. On this poolscape in Monsey, N.Y., the wow-factor feature is definitely the 12-foot-high, 18-foot-wide waterfall made of RicoRock. Inside the falls there's a 7-foot-high cave with seats and fiber-optic lighting built into the walls to create a starry-night effect. "The big waterfall took six men a month to build and that's working on it five to six days a week," says Roy Robinson, owner of Pacific Pool & Spa in Sloatsburg, N.Y.

"A lot of detail work went into that falls," continues Robinson. "The other waterfalls are simpler, and to build each one took four to five days." Each faux rock waterfall has its own circulation pump and its own fiber-optic tower. Notes Robinson, "Placing all the lights within the waterfalls and wiring them took quite a bit of time, as well."

Robinson says he likes to work with RicoRock because its allows for greater flexibility in the building process compared to working with real boulders that usually require a crane, and that can be tricky when access is limited.

The other feature on this poolscape that visitors notice at night is the lights. "Everyone that has ever seen it says it feels like you're looking at more than just a pool, that you're looking at a piece of art," says Robinson, "because it's so magnificent, especially in the evening when it's changing colors."
