HELP I don't understand

[napacook]

Ammonia is 0 and nitrite is 2.0 I don't understand we did a 80% water change about 3 days ago as ammonia was 1.0

What can I do to get this down [emoji30]

Could you provide a little history behind this tank please? The more we know about it the more likely we can find out what went on.

Perhaps check your source water for nitrites.

also 1ppm ammonia converts in to approximately 2.7ppm nitrite.

How long has the tank been running?
Do you change out the filter cartridges?

Looks like your tank wasnt fully cycled. Just rock out with 50% water changes instead of the 30% and feed oncenper day rather than twice.

Only feed once a day, freshwater fish don't need that much food. And btw eventually your clown loach will get to like 14" long.

You seemed to add a lot of fish in a short time. The tank is probably not able to cope with all the bioload increase. So, ammonia will spike until the bacteria multiply sufficiently.

I would do a decent sized WC every few days until everything is normal.
