Anyone use a DENITRATOR on your SPS system????

I run one on my 450g, it is an H&S brand-in sump- and the reason for using it is because I do not have enough room for a refugium, but if a refugium did not keep up, I would recommend using one. Patience and getting the correct size for your tank is most important when setting them up.

I dreamt of getting a denitrator years ago. These days I think protein skimming, refugiums, high coral populations, lots of live rock, high water flow, and deep sand beds offer a lot of options for nitrate removal. IMHO I believe trying to emulate nature by using it's own processes is always a good idea.
FYI though...I do not have a deep sand bed or a refugium. I have about 1" of standard crushed coral and my nitrates have always been non-detect (2 years). I have about 1lb/gal rock, an oversized skimmer that gets cleaned twice a week, 45x turnover, and won't ever have enough corals (one of these days my wife will let go of her choke hold on my livestock fund!). Also, every drop of water that enters the tank is RO.

well I just hooked mine up today. Its a schuran 100. Since I dont have enogh room for a fuge, I need someting else do help out. I will be testing every day and see how its works out. I do have a reading of 4ppm of nitrates but my p04 are 0.05 (hanna) so iam also looking in reducing that to almost 0. I have read alot about them and I think most have had good success with them so I will see what happens.
Good luck to your quest. I am taking a easier course to find out if PO4 and NO3 is the main cause of browning.
My 5 ft tank now contains no fish and I am using 400Ws lighting. Both NO3 and PO4 are undetectable and I am still running 300g of Phosban in there. I got some very colorful frags 1 week ago and some of them has faded a little. I am also doing Amino Acid, Coral Vitalizer and if the color can not come back, I guess sometimes we just can't get the same bright color as in the ocean for certain colony.
Hopefully it is the right way.
I have moved 2 friend to the Z-way and it has been almost 1 months. NO3 is now below 1 (was 13) and PO4 is now below 0.03. Some improvement has been observed but his coral was totally browned out to start with. The effect is not as advertised. Especially the 2 weeks color progression photos.

Thanks. I think that coral need some NO3 and p04 in the water to get the colors that they get in the ocean. Look at what some of the people using zeovit. If they take out to much it will kill the acros so they need to add more stuff to make up what was taken out. But I've seen pictures of your tank and they look awsome. I think maybe you need to try a diffrent K rating bulb to get the nicer colors. But let me know how thing go in your set up.
I was using full 400Ws 14,000K for a good while and it didn't pay off for me. I get much better result with 10,000K (Probably because of the intensity.) I am satisfy with the result but they are not as bright as the time I collected them in the wild although they are still beautiful. I hope one day I could find a way to keep them as bright as original.

This is some information that is well neeeded and should be look into further. I for one have always wanted to do it but just never got around to getting one. Keep eveyone posted on your results as it my help others like myself that are always looking for the edge

I don't think you need one at that low of a reading. But if you decide one one, here is a great review. There are a few other threads over in the H&S forum.

Horace - the Salifert po4 kit is essentially worthless for levels SPS keepers are looking for. Just about everyone who has bought a colorimeter or higher level po4 kit (I use Deltec/D&D and am waiting for the Elos) thought they had no po4.

I am well aware that its not accurate, however, if its undetectable, then you likely are within SPS standards. I would not use that kit to determine actual P04 levels like you mentioned. Any reading on a Salifert would indicate to me that your too high for SPS. The last time I had my tank measured via a colorimeter (before I even started using Zeo), I was reading .03 which is plenty low for SPS.
Plus I can look at my corals and tell that my nutrients are super low... I have very little zoox on my colonies...infact too few IMO.

Just pointing it out. I know your tank is very nice.
I wouldn't consider Salifert inaccurate, just not high range (or would that be low range?). I do think that .03 is plenty low for SPS but I see improved color when its lower than that.
The use of the high range test kits are for measuring effluent of po4 reactors to see when your GFO's are "full".
Anyway - back to the subject - I am buying a Denitrator for a FOWLR for a tank I am putting in a restaurant. I'm hoping it works as billed.
