Nitrate Level

Recommended Posts

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. :bow::shock:

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. :cry:

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?

:) Greeting :)

Tank: 4' by 2' by 2' (CR antique)

Sump: 3' include 1' refuigm
