  • Can't keep a steady temperature.

    By on

    I bought two of these and one the temp swings terrible and isn't near what the dial is set to. I replaced it today with another brand from PetSmart and it's the first time since I started the aquarium that my Apex Controller isn't being used as a thermostat. I pulled the bad heater out and replaced it. I am currently using it temporary when I make new water where it can't kill the fish if it runs a little hotter. I have it protected to turn off if it doesn't on it's own.

  • temperature control is completely off

    By on

    The product arrived with the little blue knob that controls temperature fallen off. I put it on in what felt like the only way it _would_ go on. Luckily rather than put it in the turtle's tank directly, I decided to use it to heat a bucket of replacement water. I set the knob to 78, left the heater submerged horizontally in the bottom of the bucket, and when I came back a couple hours later **the temperature was almost 90 degrees**. I will not put this in my turtle's tank and I recommend that anyone purchasing this test the temperature settings in a separate tank or bucket before using it in your pet's environment.

  • Life Saver!

    By on

    I had a previous heater that never got my water above 73 degrees F even though it claimed to be preset to 78. This item was only a few dollars more but ended up being astronomically better! It had the water heated up to a tropical 80 before I came home from work that night! In love w/ another in cart for another tank!

  • Finally, a heater that works!

    By on Top 25 Contributor

    I've had this 100 watt Aqueon heater for about a year now, and it works great! I've used this heater in tanks as small as 12 gallons to tanks as big as 40 gallons, and it still holds up! I usually have it set to 78°F, so this heater sure does have to work hard, however if it's been working for a year, then it must be a good heater!

  • Terrible heater

    By on

    I have 3 aqueon heaters and have replaced 2 within six months. The blue adjustment knob falls off and the calibration process is tedious and nearly impossible. Save yourself the anger and just buy AquaTop.

  • impressive well built tank heater

    By on

    We are experiencing cold weather in Florida.(Cold by our standards!) I have a small pond of 55 gallons. This heater did a fine job regulating the heat for the pond. I'm quite pleased and so are the fish.

  • Trouble x 2!

    By on

    I purchased two 300w units for my startup 65 gal tank. One as main, one for water replacement. Within a week the main did not function properly and water was 3 to 4 degrees higher than the setting. I replaced with backup and, same problem. Thank goodness I purchased from Chewy who promptly credited my account for both. Chewy gets a 10 Aqueon 0!

  • Not what I expected

    By on

    I recently set up my new 10 gallon aquarium with the 50 watt heater. When I purchased this product I was under the understanding that i would be able to set the aquarium temperature to 70 degrees. This however is not the case, I am finding out that even at the lowest setting on the heater the lowest temperature my tank can go down to is 80 degrees without just being at room temperature. I will be looking to replace this heater
