Instructions

It is recommended to fill the aquarium with water that is close to the desired temperature you are trying to achieve. The aquarium heater must be positioned to allow for free circulation of water around the glass heater tube. Generally, the heater should be placed at the rear of the aquarium, preferably close to a source of water movement to ensure even and thorough distribution of warmed water. Be sure there are no rocks, decorations or gravel obstructions touching the heater to create uneven heat in the glass tube and weaken it.

1) Select the appropriate temperature by adjusting the Temperature Dial to the appropriate degree calibration.

2) Position the heater in the aquarium with the heater mounting bracket attached. Press suction cups firmly against glass to adhere to the aquarium wall. Wait 30 minutes before connecting to the electrical outlet. This allows the heater to adjust to the aquarium water temperature.

3) Note that it may take up to 12 hours for the heater to attain the water temperature you have selected. It is only after this time that the Easy-Set Temperature Dial should be adjusted to achieve a higher or lower temperature, as required.

4) The unit heats only when the pilot light is illuminated. When the pre-selected temperature is reached, the pilot light shuts off. It will light again only when the heater is required to maintain the temperature at the selected level.

5) The temperature should be verified with an accurate thermometer after the heater has reached the desired temperature, before any fish are added to the aquarium, and throughout the life of the aquarium.

    Fluval heater

    By Bill on Oct 21, 2021

    Very satisfied. Heaters can be hit or miss but this one is working, Only 3 weeks, like it should. I am hoping this one lasts for years like the other Fluval heaters I own.

    Great little tank heater

    By LisainNM on Mar 15, 2021

    I have 3 bettas and was using the tetra brand heaters which work fine. However one of my betta tanks sit in our sunroom and in the winter at night that room is the coldest in the house and the tetra brand heater could not keep the tank up to temp. When I would wake up the tank temp would be 74 degrees and with a +/- 1 variation I was not happy with the temp being at the low end of acceptable temps. So I decided to give this little heater a try and I am glad I did! I set this heater on 80 and the tank has been 79 degrees ever since. With a +/- of 1 on the tank thermometer (I have digital probes in tank) this is acceptable and I am very happy with this purchase!

    Fish tank heater

    By Honey on Jan 17, 2021

    This is probably my favorite addition to my tank. Its modern its elegant and highly accommodating with multiple ways to position. Its a little confusing at first and does take a day or so to sufficiently do its job in my 3 gallon tank. It lights up a soft blue in the middle when it feels a temperature change in the water and fine print states it has a 3 year warranty. Im in love with this product and so far has been worth every penny. My betta seems to like it too since I caught him hanging around it a few times.

    Decent heater

    By DiscusMamma on Jan 28, 2021

    Decent heater for the money, bought a few of these as they were needed for my breeder Discus tanks. Have tried nany other heaters and have failed within 6months. So far so good.

    Maintains temp

    By Saltwater24 on Nov 8, 2020

    I bought this for my evo 13.5 gal aquarium after having issues with a different fluval 50w heater. The old heater would get way to hot and a wide fluctuation in temps. I bought this because it has a temp dial you can set. So far since I have set it up, every time I check my aquarium temp it is 78.4, never changes. Not sure why some people gave this bad reviews.

    disappointed

    By lisa on Oct 30, 2019

    I ordered this based on reviews. It worked for about 2 days and then broke. I’m quite irritated and now am in the market for a new heater.
