❤Paladin Heater: The design concept is derived from the Paladin.It like a paladin guard you fish.No cooking fish!!!
❤PTC,Ceramic core.Corrosion resistance,easy to clean,PTC , keep 1 month cleaning once, for salt water ,keep 1 month cleaning twice,can greatly extend the service life of the heater.
❤PID control:The control accuracy is ±0.5℉.

【500W Aquarium Heater】500W aquarium heater is suitable for 75 to 130 gallons of saltwater and freshwater aquariums. Voltage 110-120V, temperature control range 59-93℉ (15-34℃).
【Safety and Durable】The submersible aquarium heater is made of explosion-proof quartz glass material and high-temperature resistant nickel-chromium heating wire, with silicon carbide thermal conductivity, safer heating and longer service life. The sturdy black shell is high-temperature resistant ABS material to protect fish, aquatic life and you from burns.
【Multiple Protections】①Over-temperature protection, it will stop automatically when the set temperature is reached, and it will automatically power off and buzz an alarm when it exceeds 97.7℉. ②Power off when out of water, the heating rod will automatically power off when it leaves the water surface, and the side probe prevents dry burning and fire. ③APS anti-boiling fish system, APS automatically starts when the heating rod is out of control, and automatically cuts off the power within 10 seconds

🌷[Multi-angle Installation: Equipped with two powerful suction cups, it can be installed at any angle, whether vertically or horizontally, as long as it is completely underwater.
🌷[Sensitive and Reliable Thermostat: It can maintain a uniform water temperature and automatically shut down when the set temperature is reached, ensuring a stable biological environment in the aquarium.
🌷[Accurate Temperature Control: The temperature dial is accurate, with a temperature range from 68°F to 93°F, and the temperature difference does not exceed 1°C, which can fully control the aquarium environment.

With its unique and small size, our aquariums cooling fan wont detractfrom the beauty of your fish tanks, making it a great addition to any home or offices.
for fish enthusiasts of all our aquariums cooling fan is a necessory accessory for any fishtanks.
Designed with lowvoltage for energyefficiency, this fan is safe and easy to use with its USBinterface and DC5V direct currentvoltage.

🐠【Explosion-proof Ceramic Aquarium Heater】The heating element of the 50W Aquarium Heater is composed of the explosion-proof quartz glass tubes and high-temperature resistant ceramic heating core, using the latest submarine technology for fast, consistent, and more evenly distributed heat. Housed in of V0 grade ABS flame retardant plastic for IP68 waterproof, corrosion resistant, and high-temperature resistance makes the fish tank heater stronger.
🐟【Overheating & Out of Water Protection】When the aquarium heater head out of the water, the heater will automatically stop heating, the controller will display the “E1” until the heater is completely submerged in the water. If the water temperature exceeds 34°C/94°F, the heater will automatically stop heating, and the controller will display the “HH” until the water temperature drops below 34°C/94°F.
🐙【Precise Temperature Control System】M2 grade precision water sensor forms an accurate water temperature sensing system. Automatic Constant Temperature Function: Temperature accuracy is ±1°F, when water temperature is higher than the set temperature, the adjustable aquarium heater will automatically stop heating; when water temperature is lower than the set temperature, the adjustable fish tank heater will restart heating.
