    Life Saver!

    By Makayla on Dec 29, 2018

    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!

    temperature control is completely off

    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.

  • 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!

  • Dial set knob for temperature

    I thought the adjustable temp knob came attached? I can't snap it on and have No temp? Is this supposed to come that way? I cant snap it into place.

  • Regret Buying This..

    By on

    I got this heater because i was told i need 100 watts for my size tank. Really outraged to see that it only heats my water about 10 degrees less than what i set the temp to. Pretty useless and now i need a new one. Wish i could get my money back to go toward a better one! What a disappointment and danger to my fish!
