Help!!!!

  • We are currently upgrading MFK. thanks! -neo
What kind of filtration? A canister may spike nitrate levels if it hasn't been cleaned for a while. Yes do 30% changes and test test test. I would think that a dead fish would first raise ammonia levels.
 
Do around... 50% ... then 20% .... 20% water changes consecutively... I had to do that to remove my nitrate spike :(
