Tunze decided to remove us from their reseller list in June 2025, a decision we don't particularly understand. This product is no longer available from us, and we apologize for this.
Good news : we offer a wide selection of similar, equally effective items in our category: Algae Reactor for Aquariums
As an alternative, we offer you the AQUA MEDIC - Plankton light reactor 2 which offers good value for money.
Chaetomorpha or “spaghetti algae” is cultivated by many aquarists with the aim of removing nitrates and phosphates from marine biotopes. All you need to do is to regularly collect a certain quantity of algae, the biological balance is reinforced and represents an effective and simple alternative to the use of chemical substances or resins! For this purpose, TUNZE® has developed two specific Chaetomorpha reactors that can be positioned next to the aquarium or in an under-aquarium filter. The internal circulation of water is studied in order to allow a rotation of the culture and thus to save the number of light sources.
Seachem 's Reef Phytoplankton is a marine green and brown phytoplankton concentrate designed to provide fatty acids, proteins, vitamins, essential amino acids, along with organic carotenoids for invertebrate nutrition.
Plankton light reactor 2 from Aqua Medic has a filling volume of approx. 5 liters and is a system that facilitates the production of plankton and all this in the natural food chain.
Plankton Light Reactor PRO from AQUA MEDIC is ideal for producing your own plankton easily and efficiently. With a volume of approximately 50 liters , this reactor allows you to cultivate microalgae, fertilizer and carbon dioxide. These microalgae can then feed your filter-feeding animals or be used for zooplankton cultivation. Its integrated 50 W LED lighting ensures optimal brightness, guaranteeing rapid reproduction of algae. In 24 hours, the mass of algae can quadruple if the nutrient conditions are right. This reactor is equipped with an air intake and a regulation valve , as well as a pipe with a valve to facilitate the sampling of plankton.
