keeps the tank warmJuly 23, 2010 Bij(Prairie) I purchased this unit to heat my 2 gallon fishbowl that was home for my male Betta (Regi). The instructions are simple and it can be submerged OR put under the bowl to heat the water. I tried putting it under the bowl and found that didn't work at all. Next I submerged it in the bowl but the bowl is small and even when the unit was buried under the gravel it looked really crappy ( a bit like Homer Simpson's spice rack). So I abandoned the 2 gallon bowl and purchased a 5 gallon tank. The heater works well in the 5 gal. I would definitely suggest getting a thermometer though. It keeps the water at approximately 80, but on really hot days the temperature in such a small tank can soar so you need some way to monitor that. On hot days when I can see that the temperature is climbing I unplug the unit.
I wouldn't say that I am completely satisfied with this unit. I would be happy if it had an automatic shut-off and temperature adjustment valve. But it does work (as stated) and is useful if you have small water environments.
Great little productMay 4, 2010 G. Chen(brooklyn, new york United States) 1 out of 1 found this review helpful
This has worked fine for me and I got it for just under twelve dollars. My only problem is that sometimes I'm not sure it's working and I am not sure how it regulates the temperature... But it's worked great so far and I've had it for a month. Plug it in and it will slowly heat the tank up to the desired temperature, which I think is two or three degrees above room temperature so it helps to keep your room temperature constant and at 75-77 degrees.
Mini aquarium, 7.5 wattsApril 22, 2010 1 out of 1 found this review helpful
The important thing to know about this little heater is that it warms up to 5 gallons of water about 5 degrees above the room temperature. So if the room the aquarium is located in gets cold at night, say 58 degrees, the heater will keep the aquarium water at about 63 degrees and similarly, if the room heats up to 78 degrees during the day, the aquarium water would be heated to 83 degrees. That's too wide of a temperature range for most tropical fish. I used this heater for about a week and replaced it with a standard aquarium heater that will keep the water at the same temperature regardless of the room temperature.
Decent product - qualityApril 7, 2010 L. Logan(Savannah, GA USA) My apartment (and thus my fish tank) stays around 68 in the winter and 72 in the summer, so I bought this for the 1 gallon tank that houses my betta fish. With the heater, my fish tank stays between 71-73 in the winter and 74-76 in the summer which is a comfortable temperature for most tropical fish. I've had it for a while without any problems, although when I first got it and plugged it in I was thinking that it didn't work because it just wasn't heating the water (it was winter and the tank water had fallen to a dangerous-for-tropical-fish 62), but in reality it was working fine. It just needed a while to make a sizable difference in temperature.
Great idea for little tanksMarch 24, 2010 onlineshopper(Utah) 0 out of 1 found this review helpful
These little heaters are a good idea but mine were defective and cracked opened exposing the heating element and wires. The problem was handled swiftly and I will continue to do business with the seller.
