Nitrite up to 0.25

[Devo56]

I was away for the weekend and had my brother feeding my fish then today tested the water and everything is fine but my But my nitrites went up to 0.25 ppm I did a 15% water change. Use API test kit tanks full cycled. What the best way to lower the nitrites back down to 0?

Thank you

Just keep them low with PWCs until your BB can knock them out. Did your brother overfeed?

the nitrites wont last long then

[Devo56]

Thats my guess I'll just keep a eye on them

[Devo56]

Been almost a week still at 0.25

Do a large (50%) water change. Maybe that'll help. And make sure you're doing gravel vacs as an excess of substrate garbage causes nitrite spikes.

[Devo56]

Gravel vac on fine live sand?

[Rosenweiss]

Yeah, sure, Just don't dig as far. You can hover the vac a little above the sand to get particles.

[Devo56]

Ok I'll try that next

Don't be surprised if your water gets a little cloudy, but it shouldn't harm the fish.
