Eheim Thermo Control 50w Heater


Superior Illumination



The H80 can be adjusted between four full-spectrum UV blends to maximize its effectiveness through all phases of plant cultivation. It can also be used to grow macroalgae in a refugium tank.


By combining a unique fanless design and the compact Dense Matrix array, the H80 outputs the most lumens per watt of any Kessil fixture.


The BLUE spectrum quickly develops the frame of a plant during every stage by promoting prolific stem extension.


The GROW spectrum is designed to produce all-around vegetative growth throughout the life cycles of many different plants.


The BLOOM spectrum boosts yield by encouraging plentiful flowering during the plants’ crucial reproductive stage.


The RED spectrum is designed for tissue culture and cloning by producing maximum root growth during the plant’s whole life. During the finishing stage, the RED spectrum also increases the plants’ productivity and the quality of the harvest.




Switch the spectrum depending on the phase of the plant growth.

With the EHEIM precision heater your fish receive exactly the right temperature – in any aquarium.

Obvious ideas often are the best ones. For example, the aquarium heater as a rod. The heating rod is simply hung in the water and heats it. It is true that the principle is still the same as decades ago. But a lot has changed in the meantime. And today the EHEIM adjustable heater is an ultra-modern electronic thermal device with the best available technology. A jacket made from special laboratory glass increases the heating surface, serves as a heat shield and ensures optimum even heat emission. And no matter if you want to heat a 20 or a 1000 litre aquarium – you have 9 sizes to choose from.
