You can, but it takes a lot. With Prime (which is what I use) you have to put in 5 times the amount for it to be bad.
I am pretty sure it doesn't last forever in your tank, if you are worrying about it building up in your tank every time you do a pwc. You can just use the amount you need for the water you are replacing if that makes you feel better though!
I use the full dose for the tank every time I do a pwc and I have never had any problems.
People do it different, the main thing is to just make sure you get that chlorine out of the new water.
Good job on doing your daily pwc's!
