    Most Consistent Heater

    Posted by Brittany B on 30 Apr 2020

    My reef tank has never been at a more consistent temp than with this heater. I had read a lot of reviews but I’ve had this heater for about 2 weeks not and my temp has even fluctuated a degree. Consistent 79.2. I run a 13.5gal and the 75watt is perfect.

    Cobalt Neotherm Heater

    Posted by Suzan Garau on 15 Jan 2020

    I have become a huge fan of this new aquarium heater and have replaced all my others. I have lost fish when the glass tube heaters inevitably fail and overheat or stop working. These keep my tanks at a steady temperature, and their slim flat shape and black color look great in the tank. Modern Aquarium got my order to me quickly and safely.
