Digital Heater Controller

  • Precision Digital Control
  • LED Heating Indicator
  • Over Heating Protection
  • Safely Monitors Heaters up to 300 watts

The MAX 300 digital controller maintains your heater within a safe temperature providing a healthy and stable temperature for your aquarium. The three prong power receptacle works well with other compatible heating elements equal or less than 300 watts. You can finally rest knowing your aquarium heater has an additional layer of protection and security.

  • Over Heating Protection
    • Featuring over heat protection, in case the aquarium temperature rises over 92°F, heating will automatically be discontinued. When the temperature falls below 93°F, the heater will resume normal functions. Do not continue to use the heater if the aquarium temperature is over 92°F and the heating indicator (red LED light) remains on.
  • Flashing Alert
    • The digital display will begin to flash if water temperatures are not registering within the safe zone of 65°F-92°F. Flashing will cease once temperatures register in between said temperatures.

I wish more specs are provided

The controller works great, I wish the sensor would've been longer, or at least that length is provided in website description.
While reading other controllers reviews and specs I noticed that a good sensor length is in the 6 ft range. This one is 30 inch. In a tank like a 55 gal wich 22 inch high, if you put the sensor closer to the bottom, you're left with 8 inch of cord. In my case I ended up with hanging it on the top of my tank. The result is a big red spot light on my wall. A bit unpleasant if tank is in the bedroom.

Great Product!

I start using this product when another brand of controlller blew up in my tank
I now run ten of these units and have had zero issues. Once I found that Aquarium Co-Op carried this item it was simple switch to purchase through them as you are not going to find better customer service. I highly reccomend this product to keep a stable temp in any aquarium
Easy to read and easy to use

Wow

I love this thing. My tank tep is now staying more regular. It also gives me peace e of mind that it won't allow the heater to bake my fish. I had one do that in the past. It was not pretty. The temp prob is small enough to hide in a corner.

No longer Cooking

My heater came with a kit and for a short while it seemed to work okay. But every week as I worked in my tank the thought kept nagging at me that the water was to hot. Most times it sat at 81 degrees. But in morning it gets some sunlight and so gains some heat, even so my heater would kick on and many mornings I would unplug it and remove the top. Then, on one of my visits to the Coop website I came across the Finnex Heater Control and in short order it was problem solved. Now we are all swimming at about 78 degrees and all is well!
