- Enrichment of the water with oxygen


Macro Algae Reactor – Bioremediation for freshwater and saltwater aquariums
For the bioremediation of an ecosystem, live plants and macro algae
can be excellent biological detoxifiers.
Chaetomorpha “Spaghetti Algae” is cultured by many marine aquarists to eliminate nitrates and phosphates from the aquatic biotope. It is absolutely sufficient to harvest a handful of algae from time to time to maintain the biological balance in an aquarium – an economical and easy alternative to many chemicals or resins.
Naja Grass, Najas guadalupensis, can be grown to purify freshwater
systems, such as cichlid biotopes.
TUNZE MAR 3181 and 3182 can be placed in any filter basin or next to the aquarium without external filter technology.
The water circulation in the reactor ensures the rotation of the algae culture and thus reduces the number of light sources accompanied by strong plant growth. However, additional light sources can be added to the device as needed.
