Fish tank STINKS!!!!!

  • We are currently upgrading MFK. thanks! -neo
What do you guys recommend? I don't have a test kit and I did a water change 4 days ago and it smells worse then ever!

Without some water tests I think all the suggestions have been covered. You need a test kit.
 
I'm guessing dead fish or pieces of it trapped somewhere in the tank OR the filter. Turn your tank over and take your filter apart to see where is the culprit. First clue should be water is relatively warmer than usual and your water parameters in haywire.
