:eek: Did a test and found nitrite at 10ppm, and nitrate at 160ppm.
Did a quick water change of about 30%, will it be enough. :help2:
 
that should have brought it down, but is it going to go back up
y is it getting that high?
how big of a tank?
how many fish ?
what kind of filters?
what kind of media?
be more specific
 
If the tank is just finishing cycling it's not uncommon to see some nitrate spike, with that being said I would do 50% water changes everyday untill the nitrates fall into the top third of the scale.

Tell us more about you tank so we can give educated advice.... how is the ammonia?
 
No, keep doing water changes daily and find out what is causing the spikes, if this is a new tank never mind, it probably hasn't finished cycling, in that case just do a couple more small water changes and don't add anymore fish until it stabalizes and then add them slowly.

No. It's a linear relationship. If you remove 30% of your water and replace it with nitrite and nitrate free water, your resultant concentrations will be reduced by 30% to approximately 7 ppm nitrite and 112 ppm nitrate.

Would 7 ppm of nitrite be lethal to the (average) fish
Depends on the length of exposure and the "average" fish in question. I freak out if my tests show any nitrite. :(

Assuming you're sure of that, I can now bag on the low-waterchange crowd with utter impunity :D

In what way? I believe that small fequent water changes are the best because they keep the water chem more stable. :grinyes:
