Korallin BioDenitrator w/ Eheim 1048 Pump Information


Product Manuals & Documentation

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.

More Info:

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.

Comments: 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 purchasing the Korallin. THe Korallin has had no effect and it's been up and running for roughly 8 weeks. Spend your money on better pumps and use the DIY denitrator-it actually works.

Comments: I have Red Sea Max 65 pretty heavy stocked I have carbon reactor ,gfo reactor, bio pellets reactor , I changed stock skimmer for expensive Deltec Internal Protein Skimmer MC500 for $500, I change water regularly Still my nitrates around 20 ppm some time little bit higher So I decided to spend some more, and buy this Korallin reactor I can tell you it works it almost hard to believe but it all shows light yellow consistently. The only advice is to follow instructions and in about a week or so I assure you you will see the results. I would say it is the best $400 I spent on the system.

Comments: So for a while I was getting 0 nitrates coming out of it, but in my 500 gallon setup the 4002 is just having no effect. Even though it is rated for a 700 gallon setup. I think I will had a second 4002 and see if that makes a dent.

Comments: I've been using this denitrator for about 4 years now on 200 to 30 gallon reef aquariums. All I can say is wow! My nitrates have remained at zero. I still perform regular maintenace and water changes. Well worth the money! It does take a little longer to start working on lager tanks. Expect to clean pump every 6 to 12 months, and break down unit every 1 1/2 to 2 year and clean. Clean or replace tubing every 6 months, keep tubing out of strong light or they will clog with algea. I now sleep better at night.

0 Nitrates!

Comments: I have been running my Korallin BioDenitrator w/ Eheim 1048 Pump for 10 Months now. I don't remember what my No3 level was but it was high. I tried a fluidized reactor with biopellets (Reef Octopus)for a year and it did not work. After a couple of weeks with the Korallin BioDenitrator w/ Eheim 1048 Pump I was down to 0 Nitrates! 1 drip per second. I do use an air pump rather than siphonage, I keep it right on the same level as my sump. I did have a friend who needed a new home for his Lionfish before he went on vacation. I wasnt prepared to take it with me and aclimate it. I brought the fish home and left it in the opened bag in my sump and let the Korallin BioDenitrator w/ Eheim 1048 Pump drip into the bag. Dead Fish! rookie mistake just don't do what I did. Awesome Product.+ you can convert it later to a cal. reactor very nice.

Comments: Tried this product for one year. It does work to get to a zero nitrate effluent at about one drop per sec. I tried using a digital pump to slowly adjust the rate so as no maintain an anerobic state within the chamber. The highest rate I could get was 1.5 drops per second. This rate was too slow to drop the tank nitrates. My tank is a 90 gallon reef with nitrates getting as high as 80. Water changes would bring it down. I would need a drip rate of 4-5 drops per second to benefit the tank water. I used the smaller model. Maybe the larger one would give a higher rate.

Best $300 spent in the hobby

by
Reviewers Rating Excellent!

Comments: I've been in the salt water hobby for about 5 years now and can honestly say this is the best 300 and change I have spent out of the thousands invested.Over the years I've had my share of green hair algae, red cyano, and overall high nitrates - With feeding pattern changes and more persistent water changes - especially changing to RO water, and using a Poly filter regularly in my sump - the nagging hair algae and red slime issues have gone away.As I ventured into the world or corals however, I noticed that I was still having some issues. Even though my water parameters were good enough to ward off the pest algae, it wasn't quite good enough to maintain vibrant corals. I still had ~15-20ppm of nitrate regularly.Before trying the Korallin - I did explore the cheaper alternatives. Vodka dosing was a slow process that did seem to have a little success a few months into it, but at a certain point, I started having unexplained fish death, so i backed off. Next I tried the biopelletes in the phosban reactor. A great next step, however I found that process needed at lot of attention to keep the pellets from bunching up - adding new pellets, very active protein skimmer cleanings - and if I missed a few days of checking and the pelletes gelled up, I would have to discard all of the contents and start over.I got the Korallin Setup was a snap, but only because I had an extra aqualifter pump in stock. Water input to the device is either by gravity/ciphon from the tank above or by aqualifter pump from the sump. Didn't want to come home to gallons of water on the floor one day or stalled ciphons so I opted for the aqualifter method.Assembling the unit and loading the media was pretty straight forward. Just make sure you have some pictures of the fully assembled unit to use as a guide. The included instructions are sub par as noted by others.Once running you have to regulate the flow through the unit (valve included) to a very slow drip for a few weeks and test the output for nitrates. In my system, this only took a few weeks (whereas the biopellets seems to take a few months). Once the water coming out of the ractor is nitrate free, you can increase the rate of flow and retest. After roughly a month, I have the flow running at about the same rate the aqualifter pumps water into the unit - and am nitrate free! Corals have really responded well to the change.One note - I did learn that if you start smelling rotton eggs after the unit is up and running, it's a sign that it's time to increse the rate of flow through the unit. I expected the slow drip process to take a few months per other reviews, but after only a few weeks I started getting the smell. Increasing the flow got rid of the smell and testing output was still at zero nitrate.If you have been battling those last 20 or so nitrates in your system, doing endless water changes, stuck on chemical nitrate reduction (azno3) or your corals just don't seem to open/extend like they should - get this unit!

Comments: Assembly and setup was easy after doing a little reading and understanding how this unit works. Even after soaking and rinsing unit several times still had glue/plastic smell. What I did was set unit up and ran it for first 24hrs on 5 gal container of water removed from tank during water change, After 24hrs. moved it to tank. On intake side, I drilled 1/4 hole in center of 3" piece of 3/4 PVC. Put input tubing in the small hole. Cut foam that came with pump into two small plugs and stuck one in each end of the PVC as a filter. This also acted as an anchor to hold the input below the waterline. I will update review as bacteria builds.
