🐠1000 WATTS AQUARIUM HEATER – 1000W aquarium heater is suitable for 130 to 160 gallon saltwater and freshwater aquariums. The heater length is 10.8 inches, voltage 110-120V, power cord is 10.1 feet. Please select the appropriate wattage aquarium heater according to our size chart
🐠OVERHEATING & OUT OF WATER PROTECTION – When the water temperature exceeds 94°F or it is lower than the minimum water level, the heater will automatically cut off the power and stop heating, it will display an error code and sound an alarm until the water temperature is below 94°F or the heater is completely immersed in the water. Error code: HH-high temp; LL-low temp; AUTO shut off-out off water. Multiple protection, let you get rid of “boiled fish”!
🐠DIGITAL LED CONTROLLER – Temperature adjustable range: 59℉-93℉, Accuracy：±1°F. You can use the included bracket to mount the controller on the edge of the tank to adjust the temperature without reaching into the water. LED controller shows the current water temperature, preset temperature, working power and more warning sign of Low/ Hi temperature/ Auto shut off. Very easy to operate!
🐠EFFICIENT AND EXPLOSION PROOF – The aquarium heater is made of explosion-proof quartz glass and high-temperature resistant nickel-chromium heating wire. This results in faster water heating, safer, and more longer-lasting. The heater guard is made of high quality PC plastic to protect your fish from burns
🐠COMPLETE ACCESSORIES AND WARRANTY – This aquarium heater comes with accessories you need. Package includes 1 aquarium heater, 1 controller, 3 suction cups, 1 bracket and 1 hook. It offers 12 months warranty.
Customers say
Customers find the aquarium heater functions well, particularly for 125-gallon tanks, and appreciate its solid construction. The temperature control receives mixed feedback – while some say it keeps temperatures within 1°F of the setting, others report it being 2.5 degrees lower than stated. Heat retention is also mixed, with some reporting it heats 90-gallon tanks to 88 degrees easily while others say it doesn’t heat up tanks at all. The heater’s lifespan is concerning, with many units burning out within six months, and customers report issues with the auto shut-off feature not working properly. While some consider it a great buy for the money, others find it overpriced for a one-year lifespan.

Fish are Warm Again
I waited a while before writing this review, as I wanted to make sure that it was long lasting and durable. I love the ease of set up, operation, and the constant display of the current temperature. We will see how durable it is this winter. It is such a great price, I will get another one to take some of the strain of this one this winter.Update:This is my third of these. The first was a test. It worked great. So I ordered another since a different brand heater burned out. Then I purchased this one for another tank. All are running now. I expect they will give me years of good service. I like the current temp, set temp, and wattage display. Very good design.

Works very well
Be careful with the 1000 watt heaters. If you use more than one it will pop breakers, sometimes thermostat is off a dregree or two

Great heater
This is an amazing heater, super easy to use and very accurate with its digital screen. This product unfortunately did stop working for me after a year of use. I did reach out to Hygger and after a couple of back-and-forth emails Hygger did send me a replacement. The customer support was amazing and they stand behind their product. I will continue to buy other Hygger heaters as I set up new aquariums.Thank you Hygger team

I wouldn’t do it if I were you!!!!!!
This heater literally backed 25-30 of my Cichlids!!!!!! Before leaving for work it’s a routine for me to check the tank and feed my fish. when I return home from work approximately 6 hrs later, I walk passed the tank and noticed within 5 minutes of returning home something was wrong. Some of the fish were clearly struggling and the rest were near the bottom. I could feel the heat coming from the water of the tank. I check the heater. the digital readout out indicated 80 degrees. I checked the thermostats and they read 99 degrees. the water was fine in the morning 6 hrs earlier but when I got home. It’s clear what the root cause was the heater. Why is another question I have…….I would not recommend this product unless you like to gamble. I truly enjoyed the fish I had their were really beautiful. fish.

Heats quickly, temp control off.
It works like any aquarium heater but is way more powerful as it is a 1kW heater (for an outdoor pond). What I like is the readout that says the temperature, easy 1 button setup, readout shows wattage, auto-shutoff if taken out of the water, and the heater adjusts output based on surrounding temp. Cons – the casing for readout is flimsy, not sure how long it will last before I start getting error readings and have a useless heater, wish it was bigger (had more surface area). UPDATE: after a few months of use I have encountered some issues. The casing enwraps the tubes too much so that heats build up quickly inside and the device reached set temp quickly. It then shuts off. Also as the device gets close to the desired temp it reduces the wattage output. All this would be great in an enclosed, housed inside, aquarium but does not bode well for a pond that has a large surface area. They need to keep the thermostat away from the heating tubes so the device has a better idea of the surrounding water temp. There is another hygger that has a more open casing and that one allows for more water to heating tube exposure. The temp controller had to be placed in another casing to prevent moisture/water damage.

Perfect
This is a great heater. Use it in a pond outside keeps it at right temperature for fish to thrive in it. Easy to set up.

Good customer service
I purchased this heater in November and it failed in April. However, with very little hassle The sent me a brand new one in a few days. Aslong as that first one was a dud and this one lasts ill be happy. Heats well. Easy to use. Until failure kept the pond perfect.

Worked well until it caught fireâ¦(Update)
The heater worked very well under consistent use for about 6 months until a heavy winter came around and the heater controller caught fire. Luckily I had a heavy duty industrial air filter for that room, so it managed to clean up all of the smoke. Overall, it worked well, but I do need a replacement now or something more powerful than the 1000w heater for my 300 gallon tank.ââUPDATEââThey have reached out and provided a replacement heater with a higher wattage capacity! It has been working well and I have been very happy with their help

Lo compre para un acuario marino mediano de 280 litros….chulada de calentador, hace correctamente su función al calentar el agua y medir la temperatura, lo único medio malo es que solo puedo configurar la temperatura en grados Fahrenheit y no tiene opción para grados Celsius que aquà en MX es lo que tenemos, pero como tengo un termómetro alterno para medir la temperatura y este si trae ambos pues me facilita la conversión y confirmar la correcta temperatura, su tamaño es un poco grande validen el espacio a donde ponerlo y su color anaranjado hace que resalte, pero si tienen opción de colocarlo en un filtro externo fuera de la pecera seria ideal. Lo recomiendo, a mi me gusto y funciono bastante bien….calienta el agua muy rápido.
