Nitrites

Postby Snarfyrn » Sun Sep 09, 2007 4:35 pm

Hi there -
I took a water sample into the lfs early this week and they told me that my ammonia was 0 and my nitrites were high but to let it go, because that means my tank is almost done with the cycle. I tested my own water today and got Nitrites at 10.0!!! - should I really just let that go like the fish guy said? Thoughts...advice....??? Thanks

I always get mixed up between Nitrite and Nitrate.

They way I understand it the Nitrogen Cycle goes from Ammonia->Nitrite->Nitrate

Therefore, from that you need Ammonia and Nitrite levels of 0 before you can say that the cycling has finished for your filter.

But then chatting to others they might say the opposite, so might need for someone to say I've got it totally wrong or correct.

Your correct on that. As long as you still have an ammonia source and there arent fish in there then keep going till your nitrites drop and your nitrates start climbing! When your nitrites and ammonia are zero and you have nitrates and you still have a constant ammonia source then your about done!!

you are correct Superman - ammonia then nitrite then nitrate.

so the cycle is not finished yet.


10ppm nitrite is a very high figure considering you have fish in the tank, this is going to affect their overall lifespan & health, at the moment the tank water will not be very comfortable for them.

Oh I am sorry I didnt see the fish in your sig.....getting old....eyes not working as well

I think if your nitrites are that high you might consider a water change.
