- Large internal volume with a small footprint
- 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-1502 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-1501 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 100 liters with 50mg NO3 to 0 in 3-4 days.
Because this denitrator makes use of the design of Calcium Reactor C1502, 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 1.6kg high grade pure Sulfur (Sulphur) and crush-coral substrate.
Korallin S-3002 - Rated for up to 400 gal. Reactor height: approx. 28"; Diameter: 4.50"; Footprint diameter: 6.30"; Included filter media: 12lbs; Eheim 1048 Pump.

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.

Loving my bio-denitrator

Comments: What a great device. Very small footprint (~6in square) inside my stand where I have my sump and fuge. 180g reef display tank. Couldn't get my nitrates below 15-20 with other approaches, and would frequently spike above that level. Have a lot of rock as well as a deep sand bed in my fuge - 37g) and decided to take the plunge with the bio-denitrator instead of dealing with chemicals or typical media.
6 weeks in, my nitrates are now around 10 and dropping. Lot of trial and error tuning the flow rate as the bacteria colonization ramped up. Great product. Solid and sturdy. Expensive way to solve the problem, but one that should take care of it for the long term. Especially good if you don't have much room to work with.
Yes, I would recommend this product to my friends.

Comments: Have both Korallin calcium reactor 3002 and Korallin biodenitrator 3002 on a 120gallon reef tank. Excuisite piece of equipment, unmatched build quiality and performance of both units.
Have used numerous other similar units but nothing comes close to the Korallins.
If you are serious about reefkeeping, this is the type of product you should be looking for.
Have had no problems with leaks, and despite the very lacking instructions that come with the unit, setup is straight forward. Maintenance of this product also seems quite straight forward. I am very pleased.
To get the most out of this unit, a dedicated feedpump is a must.
Yes, I would recommend this product to my friends.
