Great question! We currently only carry one model of The 25 watt Cobalt Neo-therm heater, but the dimensions are: 6 1/2" L x 2 1/8" W x 4/5" Thick at Bezel.

Need to heat a 150 gallon plus 50 gallon sump, any suggestions?
Question by: RD on Jan 18, 2016 7:58:00 PM
Great question!
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!

  • Would not recommend very unstable By Cris on 8/13/2016

    I 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 6/8/2016

    I 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 2/21/2016

    I 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 11/10/2015

    Have 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 11/30/2014

    Its 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 9/2/2014

    slim and fits basicly anywhere in my tank. I like it.
  • excellent heater By Robert on 8/23/2014

    I hooked two of these up to my reef keeper and they are working great.
  • It could probably boil water. By Steve973 on 8/10/2014

    I 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.
