- Super-flat design. Fully submersible, modern design for energy efficient Aquarium and terrarium heating. Includes reversible holster/bracket, which allows heater to face inward or outward. See the product images to determine the best neo-therm size for your tank.
- Accurate, one-touch system. Simply set temperature between 66-96°f with one touch and the neo-therm electronic thermostat will maintain Tank temperature within +0.5°F. Led displays both set temp and actual temp, simultaneously.
- Ultimate safety and reliability. Integrated thermal protection circuitry prevents heater from overheating. If you forget to turn it off, the neo-therm will automatically shut it down.
- Virtually indestructible. Unlike cheap, glass heaters, the neo-therm is a resin/thermoplastic heater with a shatterproof outer-casing. Made in Poland and includes a 3-year warranty.
- Manufacturer You can trust. Most manufacturers rate their heaters on the ability to raise an aquarium 2-3°f above ambient temperatures. This is unreliable and misleading, as the average home fluctuates 2-3°f or more throughout the day. Cobalt rates The neo-therm on the ability to raise a tank 11°f above ambient temperatures, so you will never have to worry about overworking the neo-therm or it keeping up!

Then they began failing. One after another, they have given out on me. The worst part is their MODE of failure: They fail hot. They don't just quit heating one day. They crank up the heat dramatically, using all their wattage to make the water as steamy as possible. Fortunately, because we have thermometers on every tank, we have caught the temperature rise before losing any fish. Today was a fluke, because the 150W in our 32-gallon tank failed, and heated it up to nearly 100 degrees before I discovered it. As luck would have it, the only fish in there is a flag cichlid, which has very high heat tolerance. A month ago that tank was full of corydoras, and they would have never been able to survive that much heat. One of the nerites was able to flee the tank and find refuge above the water line, so she seems to have survived the heat event. I'm frankly amazed, because the water was uncomfortably hot to put MY hand into. That particular heater was a little over a year old.
I have lost count of how many of these Cobalt Neotherms have failed. I think that this is the FOURTH one, and they all failed hot. That's around a 50% failure rate within a 2-year period. Some of the ones that failed were less than a year old. We have these on surge protectors, so I am skeptical that power surges might have damaged the electronics. In any case, the internal thermometers in the Cobalt Neotherms keep working, flashing red to tell me that the water is a LOT hotter than the set point—as if I could do anything about it.
So all I can do at this point is replace them with glass Eheims, which don't have as good a temperature control, and are a lot more difficult to set, but on the plus side, my glass heaters have not yet gone insane and tried to boil my fish. For the larger tanks, I am considering a separate temperature controller module. The Neotherms are a great idea, and I love everything about them... except for the fish-boiling part.
