Love this heater By Lionel on 4/10/14Lionel would recommend this product to a friendAlthough the cost is slightly higher than other models, after having 4 glass heaters fail on me within the first 6 months, there is good value with a 3 year warranty.
Also nice to have a heater that has the indicator and sleek design
So far works great By Ryan on 4/7/14Ryan would recommend this product to a friendHave only been using it for 1 week but the product has been working as advertised. Currently using the heater to heat a tub to cook rock in m,y garage and the temp has bee really steady even in the morning when it's pretty cold.
Busted within 2 months of purchase By Kailua-Kona on 3/24/14Kailua-Kona wouldn't recommend this product to a friendThe 200W Neo-Therm is a great product when it's working. The plastic shell busted within 2 months of service and now the heating element is dead.
I have tried to contact Cobalt customer service, but I am still waiting for a reply.
These are very solid units!! By Sean on 3/20/14Sean would recommend this product to a friendCobalt has done a fantastic job with these heaters. I got two 200W units and am very impressed with how solid they are built. The only thing I could ask for would be better suction cups that hold them to the inside of your sump or tank.
Great product! By Luis on 2/25/14Luis would recommend this product to a friendGreat product! My temperature used to swing +-1 degree with my old heater. Ever since I put my new neo therm heater in my swings dropped to +-0.2 degree. Very accurate, indestructible, small footprint and easy to read thermometer.
Leaks Voltage By Worm5406 on 1/21/14Worm5406 wouldn't recommend this product to a friendI bought 4x 200 watt versions of these. I have now had 2 of them die and leak voltage into the tank. They not only leak voltage they both would not light their own lights and even show they were on. I took a voltage meter and tested it numerous times, and replaced it and the 90VAC in the tank disappeared. I would understand one... but two within a week time span in unacceptable.
I have had one get a thermal barrier around it in bubbles and stop heating.
I do NOT think these are what they are cracked up to be. I had high hopes for them but with 50% failure, I am sure I will be sending them all back and switching to the old standby, glass... Even though I do not wan to, I can not stand being shocked.
After I left the two bad ones outside the tank they turned back on and stop leaking voltage.
Great product By jarodw45 on 1/13/14jarodw45 would recommend this product to a friend100 watt heater works quickly and keeps water temp perfectly Set at your desired set temp.
Very happy! By Leslie on 12/20/13Leslie would recommend this product to a friendI am very happy with this heater! Easy to set up and I like that it shows if the temp of the tank is above/below the desired set temp. As always,great service from bulkreef!
Worth the cost over other heaters By Chris on 12/9/13Chris would recommend this product to a friendLove the Cobalt heater- although it's rather expensive in comparison to other heaters like it, the quality is 10x better and it's a small investment for keeping your animals healthy. It's also the first (and only) heater that I wouldn't mind seeing in the DT, it's super sleek!
This thing is great! By James on 11/26/13James would recommend this product to a friendThis is hands down the best heater ever. Compact, accurate and so easy to use. The display is clear, the slim design fits in tight spots, and it seems to be indestructible. It is not a fragile heater!
Great little heater! By Chad on 11/9/13Chad would recommend this product to a friendI bought this heater because of its dimensions. But it turned out to be one of the best heaters I've owned. This fits perfectly in the inTank Aquaclear 70 media basket. It holds the best steady temp of any heater I've owned. It's also built to last!
Super Tight Range By dac on 6/16/13dac would recommend this product to a friendUse a 50w for a 6gallon pico. I picked it up because I was in a pinch when I thought my Aqueon heater broke, and wanted a stronger product. I did not want to pay $55 but it was what it was. I can definitely say it's worth the price. The temperature swings are so stable and tight compared to the Aqueon, which swung around over 1.2 degrees/day. The cobalt is more like 0.1 degrees. And it's nice to have a built in thermometer right on the heater. I use that side by side with a digital, and the redundancy is comforting. It's also basically indestructible, so you dont have to worry about a rock falling and breaking it like with other heaters. I will certainly pay up and stick with this heater series when I upgrade to my 57 rimless.

I'm just waiting on the Apex gold to come out. I want to put an 85 gal coral frag/semi show tank together. With the Apex , can I run two cobalts in tandem or do i need a bigger heater than the biggest Cobalt Neo therm? I think its only good to 55 gallons . Plus I have the sump volume aswell do factor in.
Bulk Reef Supply Hey Tom,
I think they should be here this week :-) The different outlets have different amperage allotments but in general unless you are using two very large heaters your not going to run into any issues :-) Just for example, the 8amp outlet would be able to power about a total of 950watts. Should be way more then plenty for a 55g tank!

Will this heater shut off if it is not all of the way in the water? When doing water changes on my solana, the area that the heater will go in will be out of the water for a few minuets
Bulk Reef Supply Hi James,
It won't shut itself off (I don't know of any heater that would). You will want to unplug it before its removed from water (or if you have an aquarium controller you setup something like a feed mode to shut down your pumps, heaters, etc at the press of a button for when you do a water change).
by Debbie on March 31, 2014, @3:04 AM
Is there a calculator that helps you determine what sized heater I need for each of my tanks?
Bulk Reef Supply Hey Debbie,
There isn't a calculator as each heater is a bit different, but all of the manufacturers do have recomended size aquariums for their heaters. If you look at the full details of this page there is a quick comparison chart to help you match the heater size to how big your aquarium is.

I am in the process of setting up a 40 gallon hex reef tank, and would like to get a recommendation for a heater. I am not wanting to get the latest and greatest model. Just something reliable and not glass.
Bulk Reef Supply Hey Nick,
Most of us around here use the Neo-therm but the second most popular has to be the finnex HMO series heaters. Assuming you don't have an aquarium controller yet I would get something that has a digital thermostat as they are a lot less likely to fail (in particular in the ON position).
by Sloan on February 9, 2014, @9:04 PM
I have a 10 gallon tank right now. I also have plans in the future to expand my tank size to around 20-30 gallons in the future. If I buy the 100 watt heater now and put it in my ten gallon tank with the idea of using this same heater in the future would it be complete overkill? Would putting in this high watt output heater be detrimental on the 10 gallon tank?
Bulk Reef Supply Hi Sloan,
Thats not a problem at all. If the heater is larger it just won't run for as long, nothing to worry about!
Safety Features - integrated thermal protection circuitry shuts the heater down before it can overheat. Outer casing is shatterproof making the NEO-therms virtually indestructible. Use for freshwater and saltwater aquariums and terrariums.
Correct heater position- Vertical with heating element down, bezel, cord and button up.
- Minimum water level - Top of the bezel.
- For 25, 50, 75 Watt - 5.5" from bottom of the heater
