    Didn't hear my tank as I thought it would

    By Sarah on Dec 28, 2018

    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 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 … more

    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.

    Good product

    By on

    It's working very well. I have a 5.5 gallon fish tank. It works perfect for my small tank.

    Good for the price

    By on

    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.

    Decent heater

    By on

    This is a decent heater for very small tanks. Not good for anything more than 2 gallons but good for small betta tanks.

    Working, No issues

    By on

    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.

    Doesn't do what it claims

    By on

    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.
