  1. Okay... but there are better Review by dmd123
    Product Rating:

    I order two the the 300 watt heaters and installed them in a 300g tank. Yes I know what is recommended by most would have me putting 900-1000 watts in the tank but really in a heated house this really is not necessary and 600 watts should have been fine. After letting the heaters get acclimated in the tank, I plug in and they come on and give me a 76 degree reading. External thermometers show 74 degrees. Well I turn both heaters up by about 4 degrees each to try and get temps up to 78. Over 36 hours later no change in temp at all. Apparently these heater can not actually heat water. So I removed one heater and put in a SERA 250w that I had purchased previously from Aquacave. Within hours the temp started going up and with in the day the other fluval heater registered that the temp was at 78 and the external thermometers said 77. I then decided to order another SERA heater and replace the fluval. So currently two SERA 250w heaters for a total of 500watts keeps the tank perfectly at 79 degrees. So my long review basically is that while these heaters look cool and the features seem nice, they are mediocre at best. Order the SERA heaters insted. (Posted on 2/26/2016)

  3. Heater Review by leon
    Product Rating:

    I purchased two of the Fluval E300 heaters on March 16,2015 order number 100011091. One of the heaters work properly and the other heater is stuck at 86 Degrees Fahrenheit. I tried unplugging it hoping it would reset the heater none of which worked. I would like to exchange this defective heater for one that works properly. The heater works good when working properly. Maybe I just got a bad heater and Hopefully AquaCave will exchange it. (Posted on 4/1/2015)

  4. Sleek design, well made and temperature accurate. Review by Michele
    Product Rating:

    I really like the design of this submersible heater. The features are a plus. The LCD face alert changes color from hot to cold within 2 degrees of your preset temperature so you always know the precise temperature of your aquarium. The lever on top makes it very simple to adjust the temp. in .5 increments and can be changed from celsius to fahrenheit if you choose. The heater itself is enclosed so you don't have to worry about your fish bumping into it and getting burned or it getting broken. Moving or removing it from your tank with the adjustable bracket is a snap. (Posted on 11/11/2014)
