This Copper Three Leaf Mini Dish Tabletop Fountain is hand crafted from 100% recycled, solid copper and welded together to produce a beautiful water sculpture. You can choose to keep the bright copper finish by applying a polyurethane lacquer to the decorative pan or allow a rich patina to develop over time. The fountain works with and looks very pleasing with silk plants. The fountain runs on standard 110v power and comes with a quiet, long-lasting, powerful, adjustable-flow water pump. The fountain is recirculating and does not need an outside water source. And copper is naturally anti-fungal and anti-microbial. Despite this, we do recommend changing out your water periodically.
