Nitrite NO2

[Aaron88]

So my NO2 leaves were high so I did a water change 15gl in my 55gl tank. I re tested my water a few hours after my water change and my NO2 is still at 0.2. Why is it still high and how do I get it down?

DKH- 10
Ph- 8.3
NO2- 0.2
Ammonia- 0
NO3- 10

How old is the tank? Is it still cycling?

Yeah no one can really help much with-out knowing if its a tank not cycled issue or something else.

Don't stress nitrite isn't toxic to saltwater fish until into the hundreds of ppm. With time and patience your nitrosomonas bacteria will catchup to get it down to zero

nitrobacter beg your pardon...

I agree that 0.2 ppm nitrite is fine (whether it is real or just test error). Just ignore it.

No my tank isn’t cycling. My tank is 3 months cold.

Did anything die in the tank? Also, 3 mos. is still a very new cycle. They stabilize over time.
