Thank you so much for helping.
I feed the fish very little every second day, until I get everything under control.
I do have some dead stuff on the walls, it looks like hairy grass,used to be pink. Guess some stuff didn't survive from the move.
For now i do water changes every second day
This morning amonia 0, nitrite 0, nitrate 40
On tuesday I did 30% water change which brought the nitrate down to 20 on wednesday morning
So thursday nitrate 40, did 10% water change at night
Friday nitrate still 40
How dangerous is that?
So when should i change water next and how much?
