Cleaning the waterfall is easy, as it can be disassembled into many parts. A Exo Terra Repti Flo pump is included to provide water circulation. As a safety measure, smaller chameleons and frogs can have small stones or gravel added to the collection tank. Organic waste should be regularly removed from the collection tank to keep the water clean. Tap water should be processed with Aquatize to remove chlorine and heavy metals. Adding Biotize will help keep the water cleaner for a longer period, as well as promote essential beneficial bacteria and reduce odors associated with decomposing waste.
