Yes but DL the c02 gassing off causes the PH to fluctuate hence stressing the fish.
Discus will sometimes shed there slime coat if they are stressed. Im sure you sticking your hand in the tank to pull out prefilter sponges will spook them. I rinse my prefilter sponges under tap water and I clean my filter hoses and internal sponges with tap. The only things I rinse in tank water are my bioballs.
