My nitrate is super high in my 50g....and when i say super high i mean super high:22_yikes:. I always thought it was okay and hadn't tested for a while and then today i just decided to check things out. my nitrate was 0 so that was ok. This would explan why i've lost 2 cories probably. :( i was just wondering...if i do like a...30% water change, will that bring it down or will it just be back up again in 2 hours??? help! :uhoh:
 
Your nitrate is super high, but reads "0".....

Liquid test kit or strips?

A 50% water change should cut it in half...
 
Hahaha ooooops....my nitrite is 0. And its a liquid. 50% is gonna be hard...especially since i have to carry the pales back and forth...ugh.
 
What is the nitrate reading...?
 
like as high as it will go...
 
if your nitrate reading is over 80, then you should do 10% water changes every day until it gets to 40, and then go for 25% water changes until its down to 10. very high nitrates can cause deaths of a fish. although nitrate is not necessarily harmful as ammoina or nitrite, in high enough concentrations it can be harmful to the fish, which is why it is desirable to keep it under 20.

EDIT: 160 is pretty high...you may want to start with 25% water changes daily instead of 10%. Corydoras dying because of 160 ppm of Nitrates is very possible.
 
well i'm gonna do like a 20-30% one tonight...and i'll do one tomorrow too probably about the same amount, then thursday too (while testing too see what its at). How do i keep it down?? I do about 40% w/c's every sunday and i gravel vac while doing it?? I've never had this happen before and its been running for about 4 months. My 20g. has never had a problem and i don't know why now the 50 is. theres live plants in there too so they should absorb some of it shouldnt they?
 
You have a pretty hefty bio-load in the 50. Are you overfeeding? Healthy or dieing plants? Missing any fish? Major treatment with meds recently that may have affected your bacteria colony? Leaving veggies in too long? Swapped out too much media recently?
