Default Is there any research about water change rates?

We often talk about partial water changes. Has anyone seen any
research to quantify the needs, maekers for or the benefits of
changes?

Fish vets recommend them due to research. You can see the difference in
your fish and water quality when water changes are done often... or flow
thru system. YMMV due to household water quality though. Do a google search
and see what you find against doing them. ;-) ~ jan

Don't have time for a close read, but this doesn't look like an "against
frequent partial water changes" site:

Overview

Water changes are imperative for the health and well-being of your fish.
I have found, through many years of trial and error, that weekly water
changes of 10% provide the least amount of stress and most amount of
benefits for your pond fish. Koi on the other hand, will benefit more with
more water changes and thrive with a flow through water system.

Perhaps you could C&P whatever it was you read there? ~ jan
