Keep your small aquarium at the perfect temperature with the P25 Submersible Aquarium Heater. This 25W heater is pre-set to 76-78°F (24-26°C) for effortless, worry-free use in nano aquariums. Built with a shatterproof polymer exterior, it ensures safety and durability for both freshwater and saltwater tanks up to 6 gallons (25L).
