[maayy123]

My 8yr old tank now has nitrite levels of , 25/.50.fish are good but new fish die. Any advice on how to remove it ?

Hows the rest of your readings.

Good no ammonia or nitrate

Are you over feeding by any chance? Perhaps a water change would be helpful. Certainly couldn't hurt

 

[maayy123]

Thanks you.I will do another water change, see if that hepls

Are you sure that it is zero trates and higher trites? That seems backward.

How often do you do water changes? What filtration do you have? How often do you feed?

Nitrates build up and are removed by partial water changes. If you do not stay on top of those, you will see those levels creep up. If they don't come down, it is usually from overfeeding and/or filters not being cleaned regularly and/or detritus (poop) build-up in the tank...could also be overstocking.

You mentioned adding new fish (even though they didn't make it). Is it possible your tank was just hitting a mini cycle.

If you have it, or can get it, Seachem prime can eliminate 'trites in an emergency. "To detoxify nitrite in an emergency, up to 5 times normal dose may be used." (From Seachem. Prime )
