HG-043-300W

I have had eheim and fluval heaters and let me tell you, they do not hold a candle to this one especially considering the price. The eheim was always so annoying as the temperature you set would never match the tank temp even after countless attempts at calibration. Also, the suction cups used on them are very very weak and begin to be less effective over time. In addition to this due to the design everytime you want to adjust the temp you must stick your hands in the tank and manually move the dial (and given the fact that I could never get the dial temp to match the actual tank temp it would produce, this was such a hassle)! I only wish I would have discovered these amazing heaters sooner. Stick it in, and then you have an external control unit that you set the temperature with with the touch of a button. Truly a beautiful thing. I purchased 2 of the 300W units for my new 75 gallon build (I know I could have purchased a higher wattage but I prefer 2 individual units in the event one fails there is still a backup and if it fails in the sense that one misreads temp and overheats, it is not powerful enough to overheat the tank). I have both of them mounted behind my 3d background next to each intake of my canister filters in opposite corners and it is performing FLAWLESSLY thus far. Much like every other Hygger aquarium product, this is of the upmost quality and I am such a huge fan.

These heaters work faithfully day in and day out. I’ve been running one in another tank for about two years now without a single issue, which is exactly why I bought this one for a new setup in a different room. Temperature has stayed stable and accurate, and the heater does its job quietly in the background, no swings, no surprises. My fish stay comfortable, active, and stress-free, which is really the whole point. Build quality feels solid, setup is straightforward, and once it’s dialed in, it just works. I don’t worry about it, and that’s the highest compliment I can give aquarium equipment. Reliable, consistent, and dependable enough that I came back for another one.

Worked amazing for a few months but now throws an error code for the water being too hot, I have an ink bird on my aquarium and it’s running at 75 degrees. After cleaning the unit and leaving it unplugged for a few hours I plugged it back in it resounded the alarm and told me the water was too hot. Bought in January sensor failed in april. Was a cool product while it lasted

I purchased this heater for a new tank we called “the works” canister filter, custom acrylic tank, programable led lighting (also from hygger) tho whole nine yards and its led controller looked to be the Cadillac of heaters! And it is! However after about two months of use it would not work and the alarm for out of water would not turn off. We were extremely disappointed as it went with our tank perfectly. We decided to reach out to hygger as their other products have been amazing. We were not disapointed, they worked with us responding rapidly and provided a new filter at no charge amazing customer support from an over seas niche company. I would not hesitate to purchase any hygger item especially now having dealt with their outstanding customer service

Excellent heater, the separate temperature gage I have agrees with the temperature that I set on this. The temperature is kept much more stable in my tank with this heater than my previous one.

I've been using this for several years and it's still working great.

I am updating my review as the company reached out and is shipping a replacement. The unit I purchased had a temperature sensor malfunction. After about 2 months it kept alarming that the temperature was low. I would unplug the unit and it would read fine for a few hours then alert that the temp was low again - it though the temp was very low and did not match the temp of the thermometer in the tank. I cleaned the unit as I thought maybe something was stuck on the sensors, but the heater malfunctioned again. The company had great customer service and was very proactive in making the situation right. I will update on the progress of the new heater.

I have only used this heater for about a month now. So far, its the nicest heater I have used. I have been in the aquarium trade for a long time. It has to be one of the nicest heaters i have ever used. The only things I don't like are, the size of the heating element, and the feel of the button on the controller. The button feels cheap. The heating element is huge, I kind of wish it wasn't orange on the sides, that way it would hide better. I like how the controller shows actual wattage used, and it shows the temp by the tenth degree. Its easy to read with the white led. if it holds up well, ill definitely be buying another one for larger tank. I have this on a 46 gallon aquarium, will be going onto a 65 gallon.

Good size and easy to install. Works great

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 aquí 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.

Puedo poner la temperatura de la pecera y se mantiene en el rango que necesito.

Not consistent

esta fallando, las 24 horas esta pitando,, como se puede arreglar?? o me lo pueden cambiar???
