 Best Heater Period Jan 02, 2007
By L. H. Forbes
I am a long time fish keeper now specializing in discus. I have owned just about every brand of heater in my over thirty years in the hobby. No heater I have even owned is comparable to this one. It is quite simply far better than any other aquarium heater. Easy to set, accurate, holds temperatures extremely stable. It must be used with a canister filter which I notice the Informational Blurb does not include, but if you run a canister filter on your aquarium this is the one to own.

 Wonderful heater May 05, 2011
By ExE122
I purchased this to replace a submersible heater that was overheating the tank despite the lowest setting. Right away, I could tell that the Hydor was well constructed and made from much better materials than any other heater I have ever used. The installation instructions were a bit vague, but its not a very complicated system. Once I got it going, I was very impressed! It does keep the temperature very even and consistent according to the setting. It's also nice since its hidden away behind the stand completely out of sight. One less piece of equipment in the tank! Well worth the extra price.
*UPDATE - Demoted this to two stars. It had been keeping temperature pretty consistent for weeks, but today I went down to find all my fish were dead. The temperature had gone up to 102 degrees without warning. I checked the heater and the setting hadn't changed. I'm checking to see what kind of warranty is offered!
*UPDATE - Hydor did honor the warranty and replace this product. Unfortunately, I noticed a temperature spike once again with the replacement. This time I did manage to catch it before it killed any more fish. While this item heats very well, the thermostat is COMPLETELY useless and unreliable. One commenter on this review suggested using a separate thermostat (Hydroset was the recommendation) which I think is exactly what I need.

Works great Oct 13, 2011
By R. Compton

This ETH-300 has been working great for almost a year now. I have it hooked up to the Hydroset thermostat in my 90g male Peacock Cichlid tank. Its plumped inline to my Fluval FX5 using some 1" x 5/8" barbs. It keeps my tanks temp steady at 79°, every once in a while I'll set it to 80°. I love the digital display.
Nothing else to say...it works and works well. Just make sure you get a thermostat to hook the heater up to just just as added protection in case of a heater failure.

 Works great but short life span. Apr 27, 2011
By Jeff
These inline heaters work great while they last. I had a large oscar that destroyed my in-tank heater. I found this inline heater to be the perfect choice. Removes much of the clutter from the inside of the tank as well. That being said, the heaters only seem to last roughly 2 years. My 2nd heater has recently died after 2 years. I think I will be looking for an alternative heater. I have read other reviews saying the heater lasts 2 years as well. Not sure what the deal is with the magic 2 year mark. Great price and works great, but expect to replace it often.

Great Heater Mar 30, 2011
By T Hestand
I installed this heater on a new 75G saltwater tank. Water was about 68deg when I started and it only took about 8 or 9 hours to get the tank to 78deg. I have a very good digital thermometer and this heater keeps the tank +/- .3degs from target temp. Great heater and a good value.
