Nitrate Level

[slls]

Had been dosing AZNO3 for about 2 weeks but the nitrate level don't seem to go down. So I changed about 50% of the water yesterday however the nitrate level still very high. The polyps have not been opening for 3 weeks and I really think the problem is due to the high nitrate level.

Any advise from expert. Thx.

After 50% water change and nitrate still high ? that is serious...

hmm... what is high ? whats the reading ?

which test kit are you using. ?

Bro, are you using a skimmer? If have think better change it or reduce your LS.

I tried using AZ-NO3. I think it dramatically reduced the O2 in my tank, my LS died after 2 weeks.

Best way I suppose is to always do a water change. Got enough circulation in the tank?

I am using sera test kit and measurement was about 40ppm. The testkit is not faulty because I had tried it on fresh water.

temp :27.5

calcium : 430

I am using Jebo 180 skimmer, very sad leh.

AZNO3 is so expensive and yet it didn't seem to work.

Hi!

I've tried AZNO3 before and it don't really work for me as well...... the reason could be that I did not have a powerful skimmer. During the dosing period, I noticed that some corals did not respond well to the reaction caused by AZNO3 so after 1 week plus 2 week, I stopped completely and did partial water change.

As for to bring down the nitrate level, maybe u need to do more than 1 time partial change?!? Or u had too much LS and are u feeding heavily?

Change more water bro and inspect for any dead live stocks in yr tank

Cheers

After reading reviews here and there, AZ NO3 is more for Fish only tank. AZ NO3 is not good for reef tank... Anyone can confrm?

[Clownfish]

for AZ NO3 to work, i tink u will need a gd skimmer...

tanks usually hav nitrate probs when they r new n u dun hav very good equipments or it cld be a poor tank setup...

care to share with us ur setup? esp ur filtration method?

to remove the prob, u must remove the root of the prob
