I have a 1.5 -2 gallon tank with a beta fish and for how this heater is rated for bigger tanks it barely brought my tank up to a Luke warm temperature and if this can be used on bigger tanks I don't see how it can heat the water appropriately wen it barely warms my little tank I'm kind of sorry I bought this product but nothing I can do now
it works like a charm and my tank heated up in no time. I would definitely recommend.
I'm not sure if there was something wrong with the one I received but it doesn't work at all. I've had it plugged in for over 12 hours and the water hasn't gotten any warmer.
Since we got this heater, Squidward the Betta fish is so much more active.
This heats my 3 gallon tank very well. The only thing I don’t like is that there’s no stopping point for the heat level. When I first put it in and came home from work, my fish tank was at 85 degrees and I normally keep it around 78. The fish were fine but it frightened me a bit to realize it could potentially have been bad.
It's working very well. I have a 5.5 gallon fish tank. It works perfect for my small tank.
This is a decent heater for very small tanks. Not good for anything more than 2 gallons but good for small betta tanks.
Seems to be working so far, I've had it plugged in for a few days now, temperature fluctuates between 80-81 degrees in 8 gallon tank with no other heat source.
This heater claims that it will keep your tank water at about 6-7 degrees warmer than the room temperature. NOT. My house stays around 68 degrees and the tank stays around 70-71. Waste of money. Need to go buy a "regular" adjustable heater.
This heater helps a lot after about an hour or less, it heated up my tank to about 78 degrees it is really quick and efficient.
