Mid-Scale Volcanic Stone Water Feature The Atlantic Water Gardens 24-inch natural basalt column is a pre-drilled mid-scale volcanic stone column for pondless waterfall, fountain basin, and garden water feature installations. At 24 inches, this basalt column is the most popular format for single-column features and the go-to choice for centre pieces in mixed-column groupings — tall enough to be visually significant as a standalone feature, compact enough to balance with the 18-inch and 30-inch columns in a three-piece grouping. Versatile Scale for Garden Features The 24-inch height creates a presence without overwhelming the surrounding planting — well-proportioned for most residential garden bed and patio water feature settings. Water welling up and sheeting down the 24-inch column creates a continuous, pleasing sound level at normal MD-series pump flow rates. The natural basalt surface develops a progressively richer, darker appearance as the stone absorbs moisture continuously throughout the pond season, deepening from a dry grey-brown to a rich, nearly black wet finish when the water is flowing. Height 61 cm (24") Material Natural quarried basalt — genuine volcanic stone Core Drill Pre-drilled for 3/4"–1" supply tubing Recommended Pump MD550–MD1000 for balanced bubble and sheet effect Use With Fountain basin, pump vault, or Eco-Blox reservoir How to Install Set on a stable, level base in your fountain basin or over an Eco-Blox system. Thread supply tubing from the pump up through the pre-drilled core. Set pump flow for the desired water effect — moderate flow creates an even sheeting effect down the column sides. Combine with the 18-inch and 30-inch columns for a naturalistic grouping. Adjust column positioning so each stone's water sheet returns to the basin without overflow. Chemically inert and safe for koi and aquatic life. Ideal for Canadian garden ponds, patio water features, and landscape focal point installations.
