Using the Repti Gear Floating Turtle Island is easy. First, clean the area of the tank glass where you want to attach the suction cups. Then, press the suction cups firmly onto the glass to secure the island in place. Make sure it's stable before putting your reptile in the terrarium. When it comes to maintenance, remove the island from the tank regularly, about once a week. Rinse it under lukewarm water to get rid of any dirt or debris. You can use a soft brush to gently scrub the surface if needed. Avoid using harsh chemicals as they can be harmful to your reptiles. Also, check the suction cups regularly to ensure they are still in good condition and providing a strong hold. If the suction cups lose their grip, you may need to replace them.
