"Cobalt neotherm heater just blew up!!!"

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.
excellent heater By Robert on 8/23/2014Robert would recommend this product to a friendI hooked two of these up to my reef keeper and they are working great.
It could probably boil water. By Steve973 on 8/10/2014Steve973 wouldn't recommend this product to a friendI ordered this heater the first day it was available here on BRS. This is the coolest heater design because it's not glass that you have to handle super carefully, and it has a super low-profile design. And it fits perfectly well in the back chamber of my Nuvo 16. I thought that there could be nothing to dislike. Well, I place it in the back chamber and I wait fifteen minutes for the heater to equalize to the temperature of my tank that was at 80F. I had the heater set at 79F, so I shouldn't have seen an increase of temperature, and I checked the temperature with two different probes to make sure my reading was accurate. Flow around the heater isn't a problem because the back chambers are in constant flow. After a few hours, I saw that the tank was at 83.5F! So, maybe there's a problem with my particular unit, but it will be interesting to see how the reviews add up as more come in. At this point, I cannot recommend this heater, but if I get a replacement that is accurate, I will update my review.

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!
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!
