Bottom of pond has most bad stuff.

Not sure if you have a filter, but backwashing them and flushing the water
to a holding tank (to water plants later) is both "environment friendly"
(ugh, did I say that ???) and healthy for your pond.

I do a 1 % waterchange a day (more with the hot weather) by just opening the
filter drains.

Plants will love it, fish will love it. Win-win etc ;-)

I overflow the pond every other week or
so.
The fish enjoy this as the raised water
level allows them to get into the overhanging
grasses and nose out insects. They also get to
trim more watercress from the waterfall.

OK, I give in...water changes sound like a good idea. You convinced me.
Now
on to the real debate...

Should I remove water from the bottom of the pond? the top? just overflow?
What is best? Where does the bad stuff hang out?
