the problem is you have a small pond and a lot of fish for the size.
small ponds tend not to have enough water to be able to handle the
bioload. they need to be treated like an aquarium rather than a pond.
consider scooping up and giving some of those GF babies away.

you dont say where you are, but if your GF are still spawning this
can really foul a filter fast. the easiest way to add filtration is
either with a bucket filter or gravity filter.

here is a simple veggie filter I put together for over the top of a
stock tank.

veggie filters are extremely efficient and dont need constant
cleaning.

the foams are so ridiculously priced have you had any luck sourcing a
generic foam material that can be cut?

But the walls, etc. weren't washed as I figure I wanted
to leave the stuff on them. The water is currently very clear and tests
fine ..but then I clean the filter foams every other day, which is the
current problem.
