An LED indicator signals active heating, making it a compact, reliable solution for maintaining stable temperatures in small freshwater and saltwater aquariums. ## Description 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). Its fully submersible, waterproof design allows flexible placement, even horizontally, while the LED indicator shows when it's actively heating. If the difference between the ambient room temperature and the heater’s set temperature is more than 12°F / 8°C, additional heating capacity is likely necessary.
