I recently just moved to a new area and lost a lot of my fish in the process. It seems that fish have a hard time surviving in 100% tap water that is dechlorinated, but they survive 50% water changes, although they are very stressed and gasp for a 10-20 mins after the water change. My upside down catfish floats around like its dead for 5 mins, but is then fine. I used cycled canisters from my previous place during the move and everything seems to test fine. The only thing is that the water comes out of the tap very cloudy and bubbly, but it settles out very quickly in the water. I'm going to try to do 25% water changes from now on and see if that makes a difference, but is there any thoughts on what this could be. The temperature also is the same and I add dechlorinator to the buckets before I add them to the tank.
