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.

REVIEW
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

REVIEW
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

REVIEW
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

REVIEW
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

REVIEW
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
