Der Korallin Biodenitrator auf Schwefelbasis S 1501/3001/4001 ermöglicht auf einfache, elegante Weise und mit hohem Sicherheits- und Wirkungsgrad (Kreislaufprinzip) Nitrat abzubauen. Die Abbauleistung ist um ein Vielfaches höher als bei einfachen Geräten mit Einmaldurchlauf. Abbildung S 1501
Nitrat im Meerwasseraquarium ist eine Folge von bakteriellem Abbau organischer Stoffe (z.b. durch die Fütterung) oder wird mit dem Ausgangs-/Leitungswasser eingebracht, in welchem lt. Trinkwasserverordnung bis 50mg/l zulässig sind. Ab einer gewissen Konzentration führt Nitrat zu einer deutlich geringeren Lebenserwartung Niederer Tiere und vermindert das Korallenwachstum. Auch die Farbigkeit der Steinkorallen geht bei zu hohen Nitratwerten zurück.
Freie anaerobe Bakterien sind in der Lage, in einem schwach sauerstoffhaltigen Milieu dem Nitrat-/ oder Nitrit-Ion die Sauerstoffatome zu entziehen und sie über Schwefel oder seine Derivate bis zum Endprodukt Sulfat zu oxidieren. Der Schwefel dient gleichzeitig als Bakteriennahrungsmittel und fungiert aufgrund seiner Wasserunlöslichkeit als Besied-lungssubstrat, somit verfügen die nitratabbauenden Bakterien über eine dauerhafte Energiequelle. Ein sehr großer Vorteil gegenüber Systemen, wo laufend in richtiger Dosage zugefüttert werden muss (z.b. Alkohol) und die somit laufender Pflege bedürfen. Der Biodenitrator S4001 läuft dagegen praktisch wartungsfrei.
Zur Pufferung des pH Wertes ist ca. 1/3 des Volumens mit Korallenbruch gefüllt.
Haltbarkeit des Schwefelsubstrates ca. 4 Jahre.
S 4001: Reaktorhöhe: ca. 600 mm; Durchmesser Reaktorrohr: 160 mm; Boden 190 mm; Schutzart IP 64; Füllmenge bis 10 kg; Durchsatz intern bis 1200 l/h (Eheim 1250); für Becken über 2.000 l

Feature(s):

- Optimal efficiency through high internal recirculation and fast Nitrate removal
- Top-loading lid with detachable tubes for easy maintenance
- No feeding liquid required!
- Ultra-pure Sulfur (Sulphur) filling 99.9%
This revolutionary design makes denitrifaction easy and efficient. Feeding to the bacteria is not necessary; just put the unit into your system and let it run for a few weeks, denitrafication power will be activated once the unit is broken in.
The design is based around the C-4001 reactor and combine Sulfur (Sulphur) media with calcareous media to offer a high level of Nitrate removal. The recirculation method is far more efficient than simple single pass filters. As it includes reactor media, the pH is fully buffered and enriched with calcium before being returned to the tank.
With the build quality of the S-4001 reactor and recirculation, these offer very efficient nitrate removal. After a running in time of approximately 3-4 weeks (for the bacteria to colonize the chamber) this unit will, for example, reduce 250 liters with 50mg NO3 to 0 in 3-4 days.
Because this denitrator makes use of the design of Calcium Reactor C4001, once the nitrate problem has been solved, you can easily turn this denitrator into a Calcium Reactor with some additional parts (sold separately).
Comes with high grade pure Sulfur (Sulphur) and calciumcarbonat.
Specifications
Korallin S-4001 rated for up to 1.000 gal.

The Use of Sulfur (Sulphur) Denitrators
Over the last few years, Sulfur (Sulphur) denitrators have grown in popularity in Europe from humble beginnings in public aquaria to being used in cutting edge integrated filter systems.
Existing Methods
Before we recommend a new process to customers, we make sure we have tested them ourselves on our own systems. We have long held the view that if you design a natural system with the management of nutrients in mind, nitrate and phosphate can be almost forgotten. But with all the best laid plans, you often end up with excess nutrients. These may be due to a higher load of fish or inefficiency in the system’s denitrification abilities. Either way; even the best systems can end up with a nagging 10-20ppm of residue nitrate. The options currently available to resolve excess nitrate would normally take the route of increasing water changes, adding more live rock, or increasing things like the deep sand beds or adding mangroves.
An option that many people have tried is the slow flow denitrator. These rely on anaerobic bacteria, colonising a suitable medium and the flow of water being slow enough, to become depleted of oxygen to create an environment they can thrive in. These bacteria will then multiply and consume the nitrate in the low oxygen water. If well set-up this method can be quite successful.
Enter Sulfur (Sulphur) Denitrators
Guy Martin from Ecole Nationale Supérieure de Rennes did the original work on fresh water treatments plants, although the science may pre-date this. The work was transferred to the marine environment and used by Michel Hignette, curator of the MAAO aquarium. A pilot project was launched. Since then the experiment was done on a much bigger scale, at the MAAO, as well as in the Grand Aquarium in Saint-Malo. All of these systems have been a great success and the systems have proved a real boon in large scale aquariums where the management of nitrate is often an after thought, when feeding displays stocked with large fish with voracious appetites. After these successes, there have been many Sulfur (Sulphur) denitrators added to private aquariums across the continent.
- Simple to set-up and manage.
- Needs no additional feeding with carbon based foods.
- Works well without the cost of additional electronic control.
- Will supply additional calcium to the tank when used as per instructions.
- Units can be ran in series for management of higher nitrate levels.
- Long lasting: up to 2-3 years.
- Units can be easily refilled.
