Boy, that sure would save a lot of work. But I'm still skeptical. Are you
doing it that way? No adverse effects to the fish? I'm a newbie and
everything I've read has advised to treat water before you add it, and some
even add that you should aerate it and age it first! Thanks, Cheryl

Thousands of people do it that way because they own Pythons or other
vacuum/changing systems. It works great.

As far as aging water goes, that's 30 year old advice. Works fine if your city
water treatment plant uses chlorine, but these days in the USA most have switched
to chloramines, for which aging does squat. Just measure the Amqel, Prime or your
favorite dechlor brand directly to the tank, then add tap water.
