Feature(s):

  • 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 calciumcarbonat.

Korallin S-1502 - Rated for up to 250 gal. Reactor height: approx. 15.75"; Diameter: 4.50"; Footprint diameter: 6.30"; Included filter media: 6lbs; 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.

“Instructions”
4.0

The instruction neglect to describe the overall set-up and the schematic of the plumbing is poor. Here is my take: The pump is used to make a high flow loop into and out of the reactor from which (and to which) a slow drip of water from your tank/sump flows. This keeps the reactor anaerobic with s...Read More

“Wow”
5.0

So my nitrates have been doubling every day in my 365 gallon discus/south american tank so I had to do 200 gallon water changes everyday. I installed this denigrator last Thursday and the effluent is already coming out with 0 nitrates and my nitrates have stabilized around 10ppm and seam to be going...Read More

“Best tank purchase EVER!!!”
5.0

First, the bad: as others have mentioned, the manual is mostly worthless. Neither of the pictured hoses was included, meaning one of the valves was missing as well. Between youtube and a quick trip to the hardware store, however, those two negatives were eliminated quickly. Those two issues were an...Read More

“Expensive but really works”
5.0

Included instructions are accurate but minimal, difficult to follow and no pictures. However youtube is easy to follow. I had been struggling with Nitrates for years with my 55g. Up and down, up and down. Installed the Denitrator on 1/6/15 with tank at 40 ppm Nitrates. After it cycled (which took...Read More

“Korallin Biodenitrator”
5.0

I have had a saltwater tank for approximately 20 years. What would turn me off of the hobby were algae problems. It didn't seem to matter how many water changes and cutting down on feedings I did the algae problem was there. My tanks have been mostly 90 percent SPS and loosing a colony hurt. I picke...Read More

“Works with patience”
4.0

I could write pages about this.. It's a complicated product for most. However it does work, it is effective. I have a few you tube videos on it. Part1 &2. They help out if needed.

“Money wasted”
1.0

Ineffective. I made a DIY denitrator roughly 1.5 years ago. The PVC sulfut denitrator-the plans are in several places online- it was very effective but very sensitiv and the pumps pumping the watr to it were "cheap" and needed a lot of adjusting consistently-this was the reason for purch...Read More
