Because of its unique design, the Exo Terra Waterfall can be installed anywhere in the terrarium. Water circulation is provided by the Exo Terra Repti Flo pump (included). The waterfall consists of several parts to facilitate cleaning. For safety reasons, the walls of the collection tank are rough in order to allow reptiles and amphibians to climb out easily, thus avoiding any danger of drowning. As an additional safety measure, for smaller chameleons and frogs, small stones or gravel may be added to the collection tank. Organic waste should be removed from the collection tank at regular intervals to keep the water clean. Tap water should be treated with Aquatize to remove chlorine and heavy metals.
