Hello! I am a noobie to fish keeping and would like to know what’s going on? I upgraded from a 10 gallon to a 29 gallon. I put all the water and substrate from the 10 gallon into the 29 gallon and added the already cycled sponge filter in there. How long is it gonna take to be stable and or normal again? Also will my nitrates appear again? the pic it looks kinda dark but I would say it looks yellow irl. Any help or advice will be much appreciated! :)
