Water change question


Recommended Posts

Our tank is having a nitrite spike right now so we are treating with prime and doing water changes. What I am confused by is that after we do a 50% water change,  they SAY it should lower your nitrite levels by 50% but we see no change at all.  Is there something I am missing here?  Levels look exactly the same before and after

This seems odd.  I'd check your tap water for nitrite.  And try and check your test too.  Is it reading the maximum?

 

What if you check tank water in a cup and then do a 50% change with the cup and test again?

We have tested the source water,  which is our tap water,  and it tests at 0 nitrite. 

Yes,  the test strip is testing at maximum,  can't get any pinker. 

We are very confused

ah okay so all you know is > 10ppm or whatever.  if its at 30 and you do a 50% change then you're at 15 and it would still read off the chart.

 

I'd dilute 1 part tank water 3 parts tap water into a cup, measure that, and multiply the results by 4.  if its still maxed out I'd dilute that mixture 1 part to 3 parts and try again, but hopfully its not that bad :O.
