For the water feature we designed a multi-faceted system to carry the water to different areas. By using a 1” hammer drill, holes were drilled through weathered limestone boulders. Water could then tumble down the boulders from three sides in multiple locations creating a soothing atmosphere as you relax on the patio. An Aqua Ultaviolet Ultima II Bio-Tube filter system was installed. This superior filter allows easy maintenance and high water flow distribution.
