Size: 25W for 3 to 8 Gal Tank
This little heater is exactly what my 8 gallon guppy tank needed. It's the perfect size (doesn't take up precious room), the suction cups keep the heater in place and do not cause complete chaos trying to remove or move them, its attractive in appearance, and most importantly, is quite accurate (within 2 degrees based on testing using a digital candy thermometer). The temperature control knob is at the top of the heater making it very easy to slowly and incrementally increase the temperature in the tank. The temp has not fluctuated at all and has remained constant and steady. The little red power lamp light is easy to see without being too bright or obnoxious. I haven't put the temp strip inside the tank for fear that it might not be safe for the fish, and on that note, I guess the one thing I would have liked was a bit more info on what that's actually made of. The instructions are extremely simple and bare bones but it's not a complicated product - basically, turn the temp knob to the setting you desire, attach the suction cups, drop the whole thing into the tank, push the suction cups to the wall, plug in, check the light to ensure it's on, and check the temperature. Me and my guppies are very happy to have this heater! Would definitely recommend.

I bought two heaters, and they came in good. I used one of them for the 5 gallon tank and is was working great and after using it for a while it made my water shocking ( I would but my hand in the water and it would shock me) I didn't know it was the heater until I took it out and saw that the inside of the heater was becoming rusty and i used the other one I bought and when I found it I hit on the side of my tank and broke ( it was a light hit not to hard) Luckily there was no fish.

The heater looks neat and works well to keep my nano tank at the right temperature. My only issue is that it’s too big for 25w. It could have been more compact.

Got this to keep the plants warm in my large home made hydroponics system. As the temps started going down the plants were stalling in their growth. It occurred to me that setting the water bin on the cold tile floor might be the issue so I tried adding this to the system and it seems to be working. Plants are growing again without getting over heated by using the grow lights too much.

This is great for keeping the water in the chicken watering bucket from freezing in the winter. It has a built in thermostat and will automatically turn the heater element off and on. It is waterproof and submersible so it can safely be put underwater. Be sure to keep it submerged! Unplug it before you take it out of the bucket.. sitting in the open air will allow it to overheat quickly and can damage the unit.

The heater is a easy setup if your vision is decent. The top has a knob and the digits while visible requires good vision. Easy for me but tossing that out there. The temp gauge is easy to install and helps make sure the heater is working.

for a heater meant for a 3-8 gallon aquarium this thing is HUGE. We already have a small heater for our 5-gallon shrimp tank but the heater is starting to die so this seemed like a good replacement. Except this thing is twice the size of our current heater yet somehow heats half the capacity?! Our current one was meant for a 5-10 gallon aquarium and is literally half the size of this thing. For something built for a micro-size aquarium, this thing is way too big and that should have been very obvious to whomever designed this. Keep looking there are better options out there.

This DOMICA 25W Adjustable Aquarium Heater seems to be keeping a constant temperature in my bucket. I am using this in my hydroponic tomato bucket this winter to keep the water at a constant temperature in my greenhouse. The heater is bigger that I would like but it's doing a good job of keeping the water warm so I won't complain but it would be too big for my small 3 gallon beta tank. The suction cups are very strong and stayed stuck to the bucket when I tried to move the heater, they were easy to put back on the heater, it stays where I put it.
