Cobalt Cooked my tank By Andywagn on 5/24/2018Andywagn wouldn't recommend this product to a friendThis morning I woke up to my 50w Cobalt heater cooking my tank to a nice 96 degrees. It caused a horrible tank collapse and I feel like I just lost a loved one. If you read other reviews this issues seems to be somewhat common.
Failed after 2 months By Ted on 4/1/2018Ted wouldn't recommend this product to a friendHad a 75 watt heating a small 10 gal frag tank. Did not notice it died until the temp was at 67 degrees. Trusty old titanium was thrown in and bringing it back up slowly. Tank has about 15 frags to include a Walt Disney, fingers crossed Will never trust Cobalt heaters again....
Works well... By P on 2/21/2018P would recommend this product to a friendI actually meant to buy the 100watt Neotherm but mistakinggly ordered the 100watt Easytherm instead. The heater works well enough. However, it does not adequately heat a 25 gallon tank, despite the 100 watt tank recommendation (up to 29 gallons). For example, I try to keep my tank at 78 degrees. I have the Easytherm set at 89 and the tank temp is BARELY 76 degrees. Ordered the Neotherm, will use the Easytherm as a backup.
2 in 2 years By Dustin on 2/15/2018Dustin wouldn't recommend this product to a friendA friend recommended this heater to me. First one broke within a year thought it was a fluke and bought a replacement. Another one just burnt out. In less than 2 years have burned through 2 will not be purchasing another one.
Don't buy plastic heaters By Paul on 12/3/2017Paul wouldn't recommend this product to a friendDon't buy plastic heaters, they are prone to burn up. Check on reef central if you don't believe me:

lasted 2 months By Tommy on 2/4/2017Tommy wouldn't recommend this product to a friendSo, this was my worst purchase. I thought it would last a bit longer for $45. While it was working it was pretty unstable as well, temp fluctuated from 73-80. Awful choice, purchased a Hydor for about $16 after this failed and have not had trouble with it at all. I was hoping that spending the extra money would get me a high quality product.
Would not recommend very unstable By Cris on 8/13/2016Cris wouldn't recommend this product to a friendI purchased this heater and I Hate it. Biggest waste of money. The heater does a terrible job at keeping a consistent temperature.
Decent ehater By Paul on 6/8/2016Paul would recommend this product to a friendI purchased this to replace a still working over 1 year old fluval edge heater for my 6G nano. I got the 50watt version so a bit of a power upgrade from my old 25watt. Seems to be handling the tank fine, though it is summer time right now. But the office is climate controlled 7 days a week. Went with this version over the neotherm for a bit of cost savings.
Solid Heater By James on 2/21/2016James would recommend this product to a friendI probably overdid it by buying 4 of them for my 75g but it adds redundancy. The low profile design allows them to sit mostly hidden between my live rock. They are set to 74 degrees but heat to 76, within the margin of error as stated on the packaging. Heat wise they are staggered and rarely more than one is on at a time. BRS youtube was the convincing factor for me in buying these and i am not disappointed.
Best for the Money! By Cikdlover on 11/10/2015Cikdlover would recommend this product to a friendHave used one of these for about one year. It performs exactly like I expect. The durable casing and low profile make's it a perfect heater for my breeding Angelfish.
It works! By Jason on 11/30/2014Jason would recommend this product to a friendIts a good quality heater. Low profile and it works. Its very easy to program the temperature and see what temperature the tank is. Ive had mine over a year and no problems yet!
Nice heater By James on 9/2/2014James would recommend this product to a friendslim and fits basicly anywhere in my tank. I like it.
What length is the 25 watt cobalt beo therm heaters. Size for both please, and thank you.
Need to heat a 150 gallon plus 50 gallon sump, any suggestions?
We typically recommend between 2.5-5 watts per gallon for a heater. in your case we have several larger wattage heaters such as Finnex and Eheim which will work well for your application. Using two 500 watt heaters for example could work well!
Can you please list the lengths or all these Cobalt Aquatics Easy-Therm Submersible Heaters.
I am particularly interested in the 50W and 75W. Thank you!
The 50 Watt is 7" long. the 75 Watt is 10.5" long. We will look into adding the additional sizes as soon as possible!
