Chaetomorpha algae is used by many hobbyists as a natural way to control nitrates and phosphates in the aquarium. As the algae grows, harvesting algae is necessary from time to time to maintain the biological balance in the aquarium – an excellent organic alternative to using chemicals that is also economical! The TUNZE® Macro Algae Reactor (3181.000) was developed for this purpose, and can be placed in any filter tank, or, next to an aquarium without external filter technology, where the circulation of water in the reactor ensures that the algae culture rotates and reduces the number of light sources.
The included Tunze Eco Chic Refugium LED is a unique waterproof light with a spectrum suited for refugium macro-algae growth in marine or freshwater systems. The easy snap holder attaches and detaches the light, easily, making maintenance a breeze.
The Macro Algae Reactor also includes an appropriate sized circulation pump with silicone hosing, making for a quick and effortless install - just add algae and you are good to go. The pump spins the algae within the reactor so that all the algae can make full utilization of the lighting system to properly photosynthesize and grow.

Natural method of controlling nitrates and phosphate
Economical; grow, harvest, and re-grow over-and-over
For use internal or external
