  • Stop searching for other heaters.
Size: 300W for 40-80 Gallon
Best heater, just stop searching, this is the one. No headache, accuracy, great technology. Got mine about an year ago to fight ick and works perfectly! Im here to buy a bigger one since I upgraded my tank.

  • Great company, great products.
Size: 1000W for 130-260 Gallon
-TL;DR- Stop searching, buy Hygger, be happy. - These heaters are robust enough to keep my Golden Butterfly Koi pond a balmy 70°F all through the winter; even during extended drops as low as -10°F ambient air temp! I can walk outside with 6" of snow on the ground, and there's my pond, looking like a steamy, little oasis, with very happy, active koi swimming around. I have always been very pleased with the premium design and materials used in their products. For the first time ever, I can comment on the customer service they provide. I have purchased 3 of these 1000W heaters, among other things, from Hygger. I've only ever had an issue one time, and that was recently when one heater stopped working, for no apparent reason. I contacted Hygger via email and they responded so quickly, that I was shocked. After some troubleshooting attempts it was decided that the heater had malfunctioned. It may not have even been due to poor craftsmanship, it could have been a random power surge or whatever. Heck, sometimes stuff just breaks. Regardless, the customer care team immediately jumped into action and here I am, less than a week later with a brand new replacement heater. That's what I call amazing service. Thank you, Hygger. I have used a wide variety of Hygger brand products over the years, from indoor fish tanks, to outdoor koi ponds; I don't even bother searching beyond Hygger, and I recommend them to everyone I know. ... show more

  • Fish are Warm Again
Size: 1000W for 130-260 Gallon
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. ... show more

  • Horrible Heater - Stay Far Far Away
Size: 1000W for 130-260 Gallon
This Heater has proven itself to be a DISASTER. I will tell you, stay away from such and order anything else. I’ve had two of these heaters and the first one malfunctioned and we couldn’t get it to work as designed. The second heater, we’ve had for a few months. After coming home from work, we noticed our Blue hippo, cleaner shrimp and a few corals not doing well. After examining the situation, the heater failed to auto stop and super heated the tank to 99 degrees. After spending hours with fans and sealed containers with ice, we have lost over 3K worth of fish, coral and inverts. This heater and company is garbage, like their products. Poor quality, even worse craftsmanship. Steer clear, be warned! ... show more

  • That the heaters very good.
Size: 300W for 40-80 Gallon
I haven’t put it in the tank yet, But I also have a 500w in my 125 gal, and it works great. My water temp. is right on. So I’m expecting the same with the 300w in my 75 gal. I really like the heaters. Thank you very much.

  • Heats quickly, temp control off.
Size: 800W for 80-220 Gallon
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. ... show more

  • Life saver for my tank!
Size: 500W for 65-135 Gallon
Had an older glass heater go out and my tank dropped from 80 to 68. We purchased a Fluval from petsmart after driving 2 hours to the nearest store on a sunday. It was a 300W heater and rated for my 75G tank, however it never was able to get higher than 74.5 degrees. I ordered this heater because they didn't have a larger one at petsmart and it came in 2 days. it was able to get the tank up to 80 in just a few hours. I like that the gage is easy to read and has a ring that alerts you to the temp conditions as it's heating up. Even displays the watts it's using. The temp on the gage and my tank thermometer are within a couple of points of each other. This thing is working flawlessly and looks great as well. Hoping to return the Fluval as there's obviously an issue with its temp calibration. ... show more

  • Good customer service
Size: 1000W for 130-260 Gallon
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.
