Digital Display Controller Model
hygger 15W/25W/50W/75W Mini Submersible Aquarium Heater
Fish are cold-blooded animals, which means they can't regulate body temperature like humans and other mammals. Whether at sea or in an aquarium, they all need the right external temperature to survive. The aquarium is an artificial environment, not a natural habitat for fish. Therefore, the aquarium owner should work harder to maintain the proper water temperature.
Mini Size
Small size heater rod, 5.9ft long power cord.
Three-digit Display & External Controller
With an external controller, you no longer have to worry about the danger of wet hands when setting up. Three-digit display makes temperature data more accurate. The controller is wider than the heater itself. It feels more comfortable and convenient to use.
High Quality Material
The surface is Teflon, anti-corrosion and prevents rust. The outer shell is made of stainless steel and heats up more evenly. Heating material quartz glass + nickel-chromium electric heating wire, explosion-proof and fast heating speed.
Sealed Waterproof
IPX8 waterproof to reject leakage. Adopting fully enclosed glue filling technology, the insulation does not leak, safe and reliable.
No Leakage
It is compact and does not take up space, and can be installed in any corner without being obtrusive. It can also be placed in some fish tanks with a narrow black back hidden compartment (where the water pump filter material is placed).
FOR FRESHWATER
Easy to wipe clean, no need to disassemble, no gaps, no need to worry about fish getting stuck, suitable for small fish tanks.
5.9ft Extra long power cord, standard certified US plug.
Strong suction cup, firm and stable.
Can be used in turtle tanks.
Specifically designed for mini tanks.

I like that the heater is compact but powerful enough to heat the tank size it is rated for. The cord is a practical length. The controller is easy to use, and the temperature/adjustment display screen is very convenient, very easy to see what the current temperature is and what adjustments you have made.

I like the size and controller. I bought two of them, however one of them malfunctioned and overheated my tank and killed my fish. The other one seems to work ok so maybe just a faulty one…

I got the 15 watt heater for a 2 gallon cube. It is unobtrusive in my heavily planted tank, was easy to set, and seems to keep the water within a degree of the set point. The only negative to me is that the controller is close to the wall plug. That doesn't cause a problem since this little tank sits on a desk with an outlet within a couple of feet, but it would not be desirable with a bigger aquarium on a stand since it would require me crawling on my knees to set the temperature and the controller would also be out of sight for the most part.

This 50 watt digital heater works great. I use this one for a large round 14 gal bowl, filled with about 12 gals give or take. At 70 degree room temp it goes on about 25% of the time. Don’t take to much notice what the the cord temp says, seems not to make much sense. But the temp you set it for, once stabilized, is almost perfect. Keep a cover on any tank otherwise there is no telling how many watts you will need. I liked it so much I got a 25 watt also for a smaller tank, also works great, even goes to the same temp as the 50 set on the same number. Super small and not very noticeable. When used right, you will love this heater. I also think the 25 watt will be enough for my big bowl too, will try.

Impressed with quality and ease of adjusting temperature. Struggled a bit during our recent Florida snow event but warmed back up quickly. Easy to hide in betta tank.

Never kept the tempature stable and sometimes flat out didn't heat it was weird

I bought this to heat a small betta fish tank. My tank is 0.7 gallons....its the Penn Plax triple betta fish tank. I only have one betta however this heater fits the tank so that I could have three fish in the tank if I wanted to. This heater keeps my tank between 77 and 79 degrees F. This is a perfect temperature for bettas. The reviews mentioning that this heater does not adjust temperature properly are only partially correct....this heater is rated for tanks between 0.5 and 2 gallons....however smaller tanks will heat easier than larger ones...meaning a lower setting will make a higher temperature. So my 0.7 gallon tank heats to 77 degrees F if I set the heater to heat to 74 degrees F. My house also has AC in summer and warm heating for winter.....your temperature range my vary if you don't have central AC. If buying this for small fish bowls just test it first to see where the temperature will go before adding your fish. My betta has been happy for months now. I would recommend this heater for anyone with a fish bowl or small betta habitat. It works....looks decent inside the tank too.

I ordered this in October of 2024 and had it running on small marine tank for less than 3 months before it completely stopped working. The only thing that still worked was the temperature readout that let me know the water was 63 degrees. I lost hundred of dollars in aquatic life thanks to this piece of crap.
