    My Turtle is Warm & Happy!

    By on

    So far so good!! I purchased this item for my Eastern Painted Turtle. As I’m a new “turtle mom” I’ve actually never had an aquarium heater before. The instructions were a bit unclear, so I had to look at some videos, however, I found that I could place the thermostat horizontally in the tank. So far my girl is enjoying the balmy high 70’s and seems very happy!

    Heaters for my aquariums

    By on

    I bought two of the 300 watt heaters. Over sized for what I need, but better to have more and reduce than not enough. One for a 75 gallon and another for a 55 gallon. I keep these tanks at 84 degrees and these two heaters keep the temperature constant. I've not see the temperature fluctuate more than a few tenths of a degree.

    Great heater, bad packaging

    By on

    This heater is the gold standard. It's great. It's also 9 inches long. Chewy shipped it in a 6 for mailing tube.

    Working great

    By on

    I needed to get a new heater for a 40 gallon tank so I decided to try the 150 watt Eheim Jager heater. I've only had it for a short time but so far it's been working great. I set the temperature at 78, let it sit submerged for 30 minutes and plugged it in. It brought the tank temp up to exactly 78 and stayed there. Most of my other heaters are off by a couple of degrees, but not this one. I really like it so far. It is solidly built, has a very heavy cord and the on light is easy to see. Based on my initial experience, I highly recommend the Eheim Jager heater.

    Wonderful product

    By on

    I used this for my 40gallon turtle tank and its just what “they” needed!! Very well made! Bought the 75 gallon one just Incase I upgrade to a bigger tank in the future. I have it at 75 and it keeps it right around that temp. The dial is easy to see and it shuts off when temp goes higher. A nice red light u can see in the middle of the tube.

    Ehiem 300 watt aquarium heater

    By on

    I've had the Eheim 300 watt aquarium heater installed for 2 weeks now. It keep my 75 gallon aquarium at a consistent 78 degrees. One word of caution, the heater is very long. Verify that it will fit your aquarium. So far it looks to be the best quality heater I've used. As for longevity only time will tell.

    Durable & Accurate

    By on

    I purchased the 200W for my 55 gallon. It holds my tank at a 77.6F consistently. I do have it set two degrees warmer so it’s not 100% accurate, but I also have heavy filtration. It’s not an eye sore like some of the other heaters I’ve seen, which is nice. Well built and easy to adjust temp.

    Does not work all that well

    By on

    I was really excited to get this heater for my betta because of the tons of good reviews I’ve read. Unfortunately this heater does not keep the tank at a consistent 80 degrees like I need. Would not recommend.

    Good value!

    By on

    I've only been using this heater for a few weeks so I can't comment on how it is after long term use, but it's been working well so far. I ordered this heater in a pinch to replace a different brand that decided to quit working. It has been keeping my 55 gal at a steady temperature with no noticed fluctuation.
