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.
Korallin Korallin is a German based company who is a manufacturer of specialized aquatic components and accessories for the advanced marine aquarist.

Q
I purchased the s-3002 for an established marine 300G fish and live rock tank. After 8 weeks I am still having Nitrites and Nitrates in the output from the reactor. I followed setup instructions. Any suggestions?
When it works, it is absolutely stunning. I have a 175 gallon reef where I was struggling with my nitrates being at around 40. This thing cranked up with a tank full of fish and coral brings my nitrates down between zero and five. The only issue I have with it, is that it clogs easily. The end let ...Read More
When it works, it is absolutely stunning. I have a 175 gallon reef where I was struggling with my nitrates being at around 40. This thing cranked up with a tank full of fish and coral brings my nitrates down between zero and five. The only issue I have with it, is that it clogs easily. The end let an outlet tubes as well as the circulation pump clog with gunk very easily. Because of this, the pump ceases to pump water through the bottom of the Denitrator, rendering it useless. Unless you catch this when everything starts clogging up, you will be pumping water with the same amount of nitrates that the Denitrator is pulling back into the tank. I would say this. If you keep the thing clean and know when to check it for maintenance you should have no problems.Hide
After 1 week Denitrator is putting out Zero Nitrates! Tank is currently 30ppm. Let's see what happens in 2 months! So far so good and works as promised!
I purchased this S-3002 Korallin biodenitrator for my 2-tank (210 gallon/85 gallon hex) /1-sump reef/saltwater setup. I was told my others that a denitrator is not needed on such a large setup, but I don't want to take any chances with how expensive reef livestock can get. It works like a charm! Jus...Read More
I purchased this S-3002 Korallin biodenitrator for my 2-tank (210 gallon/85 gallon hex) /1-sump reef/saltwater setup. I was told my others that a denitrator is not needed on such a large setup, but I don't want to take any chances with how expensive reef livestock can get. It works like a charm! Just make sure to carefully follow the instructions that accompany the unit for both setting it up and breaking it in (establishing the anaerobic bacteria colony in the reactor).Hide
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.

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 sufficient turbulence to keep the bacteria happy. So the large diameter short tubing sections connect to the pump to make a loop into and out of the reactor and the small lines go to the tank (sump). I used wire ties to prop the pump up in position. I hope this helps with set-up.Hide

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 slightly down already! Though the manual is not perfect it's easy to assemble and get running. I'm very please and my fish seem to be too.Hide
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.

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 annoying enough that I normally would not give a 5 star rating, so the fact that I AM giving a 5 star rating speaks to how much I love this product and how well it works.
Cycling can take a few weeks so patience is required, but once it is cycled you will be dancing a happy dance because your nitrate export problem has just been solved without the need for a deep sand bed or biopellets or any of that other stuff. My tank is so simple and yet so beautiful. I don't even need a sump with this thing. A modified canister filter (all mechanical filtration removed), a protein skimmer, a bunch of live rock and this denitrator are absolutely the only filtration I'm using and my fish and corals are doing great! Oh and did I mention that my nitrates are ZERO despite not having done a water change in 6 months? Well not zero anymore, my tank got TOO clean and so I run this a little less efficiently than I could to keep the corals happy. Since my water changes have become all but non-existent, I do dose trace elements weekly.
With this up & running, I NEVER have to dose calcium but my alk depletion rate is a little higher than before. Dosing addresses this just fine, but I'm really after as little maintenance as possible. Therefore I am most likely going to be adding a calcium reactor in the near future. Once that is done, apart from daily feeding and weekly dosing of trace elements, I will have a maintenance-free tank. I have not done a water change in the 6 months since this unit cycled and everything is doing great.Hide
