I do 50-70% water changes every Saturday. I use Prime and for as long as I can remember, I have been putting it in after I fill the tank back up with city water from the faucet. I havent ever lost any fish due to this process, but I talked with someone today that SWEARS that its not good for the fish to be sitting in chlorinated water for the 30 minutes it takes me to fill my tank back up.
What process do you guys/gals use, or does it not matter?
