You feed your fish more than the plants can handle.
There should be a balance between fishfood and plants. If it isn't
in balance you get the green soup, i.e plants that fill the gap.

Refresh the pond, 10% each week, drain from the bottom if possible.
Use an airbubble pump during filling of the fresh water.
That doesn't bring the balance back.

Install a good filter, redude the number of fish or feed them less.
Feeding tip: 5 minutes max a day and they should eat it all in that
time.
The fish are well capable to survive a week without food.


I have a filter and pump that can handle twice the volume of my
pond.

Big filter is good. But many people clean the filter to often. The
filter shouldn't filter, it should provide a good place for bacteria
to do their work in converting fish stuff into plantfood.

My fish always eat everything I feed them, so I think I will
have to insert more plants and do water changes. What is an
airbubble pump?

An air pump with a bubble stone on the end. Often tap water contains
gasses that is bad for fish. The bubbles expel those gasses.
