Cleaning is easy, as the waterfall can be dismantled into several parts. An Exo Terra Repti Flo pump is included to provide water circulation. As a 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. Adding Biotize will help to keep the water cleaner longer, as well as promoting necessary beneficial bacteria and reducing odors associated with decaying waste.
