EMERGENCY a lot of fish missing

[SudzFD]

They use the api test kit. If we set the light off the schedule and turn it on white it resets, sorry. It’s an aio aquarium filter that runs bio balls, carbon, filter sock, and sponge. Ammonia 0, nitrite 0, nitrate is oddly low which is 0 but I don’t think it’s bad right? Phosphate 0, ph 8.2, calcium is 440. Every Invert is doing fine.

Did I miss something? How old is this tank?

Nitrates should not be zero in this setup.

Has the tank cycled?

Don’t worry nitrates are actually 4 it was just disease
