The Macro Algae Reactor 3181 by Tunze is the latest in macroalgae cultivation designed to offer effective energy-saving technology for the removal of Nitrates and Phosphates in Saltwater aquariums.

The Tunze Macro Algae Reactor uses a 9w Eco Chic LED with a spectrum designed for the growth of macroalgae. The specially designed chamber allows the macroalgae to circulate and rotate within the reactor to increase the contact time with the LED light but decreases how much light is needed.  Additional 9w Eco Chic Refugium LED’s can be purchased separately for the Tunze algae reactor if required.

Key Features:

• Dimensions: 233mm x 195mm x 422mm
• Suitable for aquariums: 100 – 600 Litres
• Flow rate: 500 – 1200 LPH
• For in-sump use or external use
• 20w Pump

In the box:

• Tunze Comline 2500 Circulation Pump
• Tunze Basic Controller
• Silicone Hose
• 9w Tunze Eco Chic Refugium Light

Additional to removing Nitrates and Phosphates the growth of algae such as Chaetomorpha also provides a safe haven for zooplankton to colonise providing rich natural food for some fish and corals.
