[Jfishwild]

My nitrates are crazy high. And I can not get them to come down. I have down big water changes added micro allergy. Just can’t keep it to come down. Starting to drive me crazy. I have a skimmer that’s is rated for a 300 gallon tank mine is only 135. I have ran uvs. I have pretty much have done everything but doss vodka. My levels are
Nitrites - 0
Ammonia - 0
Nitrates 100
Calcium 460
Alk 9.6
Ph 8.3
Salinity 1.025
Temp 78

Everything is where I want but the nitrates. Help me out.

Are you using a sand siphon as well?

What test kit are you using?

My first thought as well. Are you noticing any ill effects on your animals? If not, then I would order a new test kit and see what you get.

Please would you post your PO4 level.
Have you tried refugium or dosing carbon?

I had crazy high nitrates on my 75g. Beat my head against the wall several nights trying to fix the issue. Finally, I bought a kessil h80, created a refugium, and through in some chaeto. Within a week and a half my nitrates were are zero and holding. I havent done a water change in 8 weeks and still holding at zero. My recommendation, do a refugium and make sure that the light your using in it is as strong, or stronger than your display lights. Nitrates will plummet quickly.

I had the same problem on my d tank. Turned out to be the sand bed. It was quite nasty. I know you said you have sand sifting fish and all, but I would start vacuuming it to see if that helps.

Good luck.

Not enough my friend! Get yourself a sand siphon, your LFS and Amazon has plenty of them, its a big tube and basically through the suction sucks the sand up and itll twirl in the tube and the dust/detritius will be sucked through with the water, you wont lose sand dont worry about that it falls back out of the tube gracefully.

Trust me after you do that you will see a change I promise.

Youtube Sand Siphon and you'll see exactly what i'm talking about.

Refugium with a good light fixed mine. The light is critical.

 

[ZaneTer]

Refugiums really are a great way to get a handle on nutrients. Just be a little cautious as you can sometimes bottom out with aggressive use of a refugiums.

Just combine all the comment up here from easy to harder.
1- Vacuum the sand. You can do it anytime any day.
2- Couple big block Marine Pure in the sump. This is my opinion, you can google it.
3- create the refugiums.

Refugiums , Refugiums , Refugiums I never though that they will work so good with a magenta kessil light, in less than 3 weeks my nitrates went down from 60 to 0,0 , you should try it with any other light to start, but the kessil have been giving great result to a lot of persons.
good luck

salifert test kit

My salifert kit was posting crazy high levels despite my very best efforts to reduce nitrates. I tested again with Red Sea, API and Exact iDip and found that my Nitrates were MUCH lower!

 

[ZaneTer]

I have heard this can happen when nitrites are detected it will give a false high reading on nitrates.

 

[nosmok]

Correct, but an established tank should not have nitrites
