are my nitrates too high at 13 ppm ?

[acropora4u]

PO4 - 0.03 nitrates at 13ppm alk at 8.0 ... worried about the no3 at 13ppm... what do you think? calcium is at 440 , mag at 1320 ph at 8.1 to 8.2 temp steady at 77.9 to 78.1 salinity at 1.026

What are you keeping in the tank? Those parameters don't really look bad to me.

 

[shadow_k]

I see a lot of people with sps tank keep there nitrates between 5-10. And LPS and softies like around 10-20.
How the corals looking ?

Looks ok to me what is your phosphate?

 

[Cantusaurus]

Hmmm. I think it should be fine. Additional Biomedia could help, but it would probably take time. I wouldn't worry about it honestly. Trying to make drastic changes could lower the phosphate too low (which is pretty bad). Nitrates at that level should not necessarily be a bad thing. If colors are good and inverts are healthy then you should be ok.
You could also try NP Bacto Balance which is a Carbon Dosing solution by Tropic Marin (very safe to use). And it essentially helps keep NO3 and PO4 at a better ratio.
It also has some Trace Elements too. I would recommend using that.
Tropic Marin's carbon dosing options are pretty crazy, and very underrated.

phosphate are 0.03

only acropora

i am keeping only acros.. corals look good, polyp extension is short though and i am think it may be the nitrates but dont know

only acropora

 

[elorablue]

13 is spot on imo.

 

[sixty_reefer]

Those parameters look perfect to me

 

[BiGGiePauls33]

My no3 is 55 and po4 is 0.08. Depends upon the tank I guess.
Polyp extension for reference.

here is the latest pic of tank

The simple answer is probably not, but the more complex answer might be yes. There are PLENTY of SPS and even lots of acropora that don't care at all about nitrate in that range. Some, however, will be harder to keep and can die at the first sign of stress. Please don't think that all SPS and even all acropora will be happy, sad and thrive at the same levels of residual building blocks... that is just not true at all. If your stuff is happy, then you are fine.

No

 

[NemesisAqua]

my tank is lps/softie dominant and my nitrate generally sits between 10-20ppm, and has even went up over 160ppm once or twice, never lost anything, and all but one of my corals is doing great. i do have two sps frags in my tank as well and they seem to be doing just fine as well.

 

[ScottB]

If those numbers are consistent then they are fine. The majority of acropora will be fine with it. I wouldn't change the whole thing to sort out one acro that prefers something different.

What nutrient levels are "ideal" also varies based on throughput. Heavy in / heavy out can run leaner on nutrient. Feeding several times per day means you can run lower residual nutrients. (Personally, low PO4 scares me but I am a wimp.)

 

[Lost in the Sauce]

I run Lps and mushrooms mostly so a Totally different boat than an acro dominated tank, but these threads crack me up.

.338 no4

52 no3

55?!! dang! That’s amazing!

 

[hsosa]

before u worry about ur parameters look at the corals from there if u think there s a issue test. then do a. ICP test to verify your test .
