Re: [APD] Fish breathing heavily after water change

The temperature of the incoming tap water here is 
15 to 25 F above the usual temperature of the 
year round normal. The temp of my fish room tanks 
runs about 72 to 76.  Right now the ground water 
measures 85. The solubility of O2 in this water 
is far less than usual. One might take this in 
mind about gasping after a water change.

Change as much water as often as you can!
