Cobalt Aquatics Neo-Therm 200 Watt Aquarium Heater with LED Display

We're pretty picky around here when it comes to aquarium heaters. In our lifetime in the hobby, it seems like we've tried almost every one out there. We've narrowed down our list of "awesome" heaters to just a scant few, and this one definitely makes the cut! 

Packing a lot of high-end features at a reasonable price, the Cobalt Aquatics Neo-Therm electronic heaters have an accuracy of ±0.5ºF. That's really impressive- and important when you're keeping demanding fishes like Discus and some Apistos.  The electronic thermostat has an ultra-fast response time that helps to keep the temperature from fluctuating wildly. The super-slim profile is terrific for nano aquariums and crowded sumps. It's as sexy as a heater can be! The black outer casing is shatter-proof, which makes the Neo-Therm extremely safe in daily operations. 

All-in-all, one of the best aquarium heaters we've ever used! We think you'll agree, too!
