Using the Reptizoo Reptile Drinking Waterfall Fountain is easy. First, decide on the installation method. You can either use the adhesive backing to stick it in place or use screws for a more secure fit. Once installed, fill the fountain with clean water. Plug in the pump, and you can adjust the water flow to one of the three levels according to your reptile's needs. To keep your reptile healthy, make sure to refill the water regularly and clean the fountain frequently. When cleaning, unplug the pump first to avoid any accidents. You can use a mild cleaner to remove any dirt or algae. Remember to check the pump regularly for any blockages and make sure it's working properly. If you have any questions, refer to the instruction manual that comes with the product.
