Better to keep the fountain with enough water all the time (the pump should always be covered with water). Due to the reflection of water and sunlight, there may be a slightly different color between the picture and the actual items. Because of the photo effect, the fountain in the picture will look bigger than the real fountain. Please make sure of the size before placing the order. This is not a real rock fountain, it is made from resin. It is as durable as a rock but lighter and more portable than a rock.
