New Nitrate Removal Korallin Sulfur-Based BioDenitrator
 

Korallin BioDenitrator S-1502, S-3002 & S-4002
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 sulphur filling 99.9%
For fresh and saltwater use
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 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 C-1502 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 C-1502, 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 high grade pure sulphur and crush-coral substrate.

The Use of Sulphur Denitrators
Over the last few years' 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 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 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.

What do you guys think?

Probably the best nitrate reactor you can buy, works really well and easy to set up and use.

Do you have one?

I'm picking up one this week. I'd be happy to update everyone as things come along.

pls do, Do anyone foresee any negative affects

My only concern is, after 2-3yrs then what? you refill it? what happens in the mean time while you're waiting for it to break back in w/ the new bacterial colonization. This sounds like it may do away w/ a lot of things, ie skimming? It would allow us to remove the bad w/o removing the good, a continuous debate about skimming. I would love to know more about this, altho when i search i do not find much info.

Yep, i have got one, although it is not in use at the moment as i have no nitrates in my tank I ran it for about two years continously.

kreef.

kreef, could you please explain further on your experiances w/ it? Continue use of skimmer? if so how did your skimmer respond and was its removal greater or less effecient?

How long before you noticed a difference, how fast did it drop? Ease of use/setup? sorry for all the questions. Korralin seems to deem necessary to finally let us in on what you guys have over there.

No problem, ask away. The unit is very similar to a calcium reactor. The way i used it was the inlet tube,as in air line tube was in the main tank as a gravity feed, and the outlet tube can be run back to your main tank or to a sump.
The beauty of this unit is it has a recirculating pump.so no need for constant adjustments

If i remember correctly, i calculated a turnover of 10+ gallons of nitrate free water per week.

kreef.

do u happen to have any pics of it setup?

Sorry no. There are onlly two lengths of airline and a plug. :p

This is the website i bought mine from, it shows a pic of it.

It seems one of my posts went missing when the server went down.

T.T. I cant say i noticed any change in the way the skimmer functioned.

Once the unit is set up and running it takes about three weeks for the anearobic bacteria to kick in, then it produces nitrate free water. My tank was running at 50ppm even with 15% water changes per week. At a guess it was down to zero after a few weeks. hth.

Do you know of anywhere we can get one in the US..??

There was a site in the U.S. called marine monsters that stocked them.

marinedepot.com carries them now as well.

Here's info on sulpher denitrators,

[url]http://mars.reefkeepers.net/USHomePage/USArticles/SulphurDenitrator.htm[/url]

The director of Mote Aquarium talked about these at a club meeting. After adding one to a large FO public aquarium he said that nuisance algae fell off and virtually disintegrated. After looking at the unit it seems to be a simple diy, five gallon bucket with a drain on the bottom.

I just read the artical ( thanks for the link Agu ) ..I reckon that the final retail product has taken care of the "acid water" problem by including a calcium substrate to the chamber?? If I looked at it right?? It is a pretty expensive piece of hardware though.. But then what isn't in this hobby ( LOL ) I'll have to ask about it when I make my next trip up to Atlanta....

It appears that this is a "stand alone" piece of equipment with a relatively small footprint... Did I get that right?? And I'm also woundering if there would be any issues when using a calcium reactor "with" this unit also running.... I think that I read that you could use this unit "as" a calcium reactor "after" nitrates are removed... Kind of confusing to me because I'm not thinking that you will ever get "rid" of nitrates... You'd just keep the levels down to almost zero "while" using this denitrator.... Did I miss something?

Fishman. Have a look at the unit on the marine depot site to see what it looks like.
The unit measures 6 ins width 16 ins high.
There is no problem in running alongside a calcium reactor.

When using the denitrator it brings your water to zero,and then sucks up all the nitrates that have accumalated in the sand and rock,then it is possible to switch it off.

To use it as a calcium reactor you have to empty it and fill it with calcium media,but you have to buy and fit a separate top to the unit.

kreef.

Ok ... thanks ... It looks to be a stand alone unit... ( sorry I'm so dense ) I've got no room in my sump for anything so if I'm adding anything else to the system, I've got to know that it's something I can run "on it's own"....

Looks like something I'd very much benefit from having....

Thanks

So what is the verdict on this product?

As soon as i hvae some money i am going to be getting one. If i can keep nutrients at zero all the way around i can't imagine having anything less the a beautiful tank.

As I recall from looking at the DIY unit the effluent from the sulphur bucket was dripped into a second bucket of calcerous material and that effluent dripped in the the sump. Since the water exiting the sulpher was acidic it actually dissolved the calcerous substrate and worked like a crude ca reactor.

However if you clean up your tank the chemical reaction is reduced, the sulphur effluent is less acidic, and you'll stop adding much calcium back into the tank. Since this was used on a large FO system there wasn't a need for ca so that wasn't an issue.

couldnt something similar be made from a phosban reactor tube and fill it with the same materials and get a pump to feed it? $365 seems a bit steep for what u get.
