Macro Algae Reactor 3181 – TUNZE

The TUNZE Macro Algae Reactor 3181 is a compact and efficient reactor designed for cultivating macroalgae in marine aquariums or aquatic plants in freshwater. It provides natural biological filtration of the water by reducing nitrates and phosphates, while enriching the water with oxygen and serving as a refuge for zooplankton. Ideal for aquariums from 100 to 600 liters, it combines performance, simplicity, and autonomy.

Technical Specifications

Main Functions

• Cultivation of macroalgae (Chaetomorpha, Ulva, etc.) in seawater
• Cultivation of aquatic plants in freshwater (e.g., Najas guadalupensis)
• Natural reduction of nitrates (NO3) and phosphates (PO4)
• Biological filtration without chemicals or resins
• Production of live food for fish and corals
• Refuge for zooplankton and microfauna
• Enrichment in dissolved oxygen

Operating Principle

The MAR 3181 operates on the principle of bioremediation: macroalgae consume the aquarium's excess nutrients (nitrates, phosphates) to grow. This process naturally purifies the water and stabilizes the tank's biological balance. The internal circulation created by the pump ensures uniform rotation of the culture, promoting rapid growth while limiting the number of light sources needed.
