Hey, didn't know where this belonged but it had to do with filtration so....
was reccomended this for my HIGH nitrates (100
). Anyone know if it works? Better/= a refugium?
here the description:
Description
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 crush-coral substrate.
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.
Sorry for wall of text

You need to find out what is the cause for your high nitrates and fix that first. That will take care of the need for this contraption. You may overfeed, don't do large enough water changes etc.
How old is your tank, what size is it and what are it's inhabitants?

The device is way too much technology for the problem of too high nitrates. It's much easier, and cheaper, to do as Spiderwoman suggests-get a stable tank, give less food, more water changes, insure a proper number of inhabitants, maybe have some macroalgae. Basic, concientious, reefkeeping (or fishkeeping) is all you really need to take care of your tank!

Here's my stock list ( equipment to, had the list handy
) Not asking you to read it all, just in case information is nessacary. Tank is 22months old, feeding is minimum(they eat it all quickly, 3 times a week), 125g. Unfortunatly, water changes are pretty much just topoffs with calc. and elements added. ONly thing i can think of causing would be dead spots( 1 Koralia 4 broke so one side isnt getting much flow), sponges in filter(very disgusting, changed a few today andwill work on gettin other ones out.
Corals:
Mushroom Coral (doing pretty good, not alot of growth but great polyp extension)
Blue star polyps ( alot of growth when I first got it but its covered up the rock its on and hasn't moved onto other rocks)
Cabbage leather ( prob. only coral thats done well, quadtrupled in size, 4 nice frags)
Would have tons more but most mysterioulsy died a few months ago.
Fish:
Pair Clarkii clowns
3 Green Chromis
4 Pajama Cardinals
Royale Gramma
Coral Beauty
Inverts:
atleast 6 HUGE bristle stars
3 HUGE peppermint shrimps
1 MASSIVE Sally Lightfoot ( like, 1 more inch and you could eat her)
Few snails, should be lots of Nass. snails (like 60-100) but have never seen them.
Equipment:
Solaris LEd lighting G series
125g non- reef ready tank
Prizm skimmer rated to 100g ( highest I could get)
Overflow down to 150 proclear wet dray with crappy skimmer that comes with it.
HOB CPR refugium, promblem is its facing a wall nad behind a tank so it gets little attention. Basically full of crappy sand. Goingn to disconnect it.
2 Hydor Koralia 4's with 2 maxi jets ( 295mph each?)
2 Heaters (not sure which kind)
Total turnover is is about 20x water volume.
Live rock: About 200 pounds
Live sand 6" deep, somewhere between 600-700lbs PLaysand unfortunatly so it has silicates( not a problem any more) and an ugly brown look.
Thanks
Jake

From what I can tell, you need better skimming and just overall cleaning and maintenance on the existing equipment. What type of media do you have in your wet/dry? Does it have bioballs (if yes, when did you clean them last)?
More flow wouldn't hurt either. Not sure about your DSB, could be that it's not constructed correctly and now the nitrates are leeching into the water column.

Most likely not contructed correctly, when I did it there was not alot of info, mostly people saying its better to have a dsb, so I did, any ideas on how to fix it? Ill try the flow thing.
Now this seems like it not about equipment anymore, too bad you can't move posts.

I agree with spiderwoman that in a matter of generalities, throwing equipment at a problem is not solving the problem but rather covering it up. So by saying this, I am going to reiterate that what she said still stands. Sulfur based and anerobic based denitrators are supposed to be pretty effective at reducing nitrates in a healthy system to slow the buildup of nitrates, theoretically reducing water changes. I've not used the device myself, but I have been eyeballing it as a potential time and money saver by reducing (NOT eliminating) water changes.
In your case, your skimmer is a suprise to me. You've obviously got some money to invest in your hobby given some of your equipment choices, so I'm curious why you chose such inexpensive skimmers. I'd suggest going out and investing in a good skimmer (Euro Reef, ETSS, MRC, Deltec, etc). You'll be suprised when you see what your old skimmers have been missing.
Apropos... play sand contains silica, not silicates, so it never was a problem.

there wasn't alot of choice in the way of skimmers and didn't know which ones were good. Definatly, will look into that. Didn't know about the silicate thing..... interesting

I really like the skimmers you suggested, not sure how'd i'd fit it in though, seems more simple to get a new sump with the built in skimmers from ETSS but not sure if that would be too much change. Maybe im making it overly complicated. Dunno.

I hate buying things that do lots of things... sumps that are also skimmers, alarm clocks that are also tape players, etc. You usually get one product that does two thing rather crappily. Worse, when one thing breaks, you have to replace the whole thing.
I don't know what size tank you have, but on the advice of others here, I put a (hugely oversized) Octopus DNW-110 skimmer on my 24 nano a few months ago and I absolutely LOVE that skimmer. They are awesome skimmers for the money and are relatively compact, you may look into those, perhaps one of those will fit better.

I'll look into the octopus skimmer. Sorry if I mis-lead you, its not a 2in1 its a sump that has one of their skimmers attached, not like a skilter, but like it already has it attached.

wow.... just retested with fresh test kits, amm. is acually 0 and nitrates are 15.... does that change your suggestions any?

Well how did you get from 100 nitratres to 15?
A good skimmer is a nice thing to have, period. If you solved your nitrates another way, that's great, but you still may consider upgrading in the future.

New tests over old ones, no real way...... looking into getting one of their complete filtration systems, ETSS Evolution 500 skimmer with refugium. Looks good, what do you think about them? cant post the site unfortunatly soo....
