How to Build a Fish Pond Part 4 - Finished Pond
Nov 8, 2026
Part 4 of a 4 part series on how to build a fish pond.
This video shows the finished pond working and explains the workings of the pump and filter system. It also has the finished rockery which will get planted up in the spring.
Stay tuned - the end has some out-takes.

The pond will be drained out and refilled to remove any cement residue, then left running for a couple of weeks before adding the fish.

Thanks for watching.
Hello there, welcome to part four of how to build a fish pond
This is basically just a short summary of how we finished the pond off
uh it was more or less finished in part three
but i'll run through what we've
done just to give it the finishing touches
obviously now the pond is full uh you can't see any
of the black line around
the edges so it looks a lot better water kind of
comes halfway up the rockery stone there giving it
a nice natural edge this will
allow the water to drop maybe two or three inches or so before
Before you start seeing the black line around the sides
Meaning that you don't have to top it up,
you know, every week in the summer
It'll go a long time between top-ups
We brought a load more rockery stone this morning.
And we've basically just dug it in around this mound here
We've taken a lot of the grass out of the mound
Because unfortunately, the dude that dug it out
instead of removing the grass first
and putting it in a pile and then digging all the soil out,
he decided to dig the whole lot out together
and just clash it all in one heap.
So we've had a hell of a job digging all the
The grass out of here, there will still be grass in here
so I've advised the folks I'm doing the
job for just to leave it till the spring.
We're in the back end of the year now, it's late October
Just leave it till the spring, wait till the grass comes up
spray it off and then plant it
We did put that plant in there,
it was actually grown out of the heap of rockery stone that we
brought. This is the pile of grass that we've dug out
of the pile whilst we've been shaping the
the heap. There will be at least
that amount still in the pile unfortunately
Walking around the back of the pile,
you can see the odd rockery stone plugged in there.
We'll just kind of put them in randomly.
The last thing you want is something that looks contrived.
Obviously, the pile of soil is still pretty rough,
but it's been raining overnight,
and to wander around on there would just make it like a total quagmire.
It would be a hell of a job.
So I'm going to leave it for a week or so,
come back, plant the pond up,
and rake all this, hopefully when it's dry,
and give it a really neat finish.
Cascades looking nice.
Pretty natural sort of effect.
Hello you know we have obviously put spill stones
in there it falls quite well and really oxygenates
the water quite nicely.
You cut the liner and underlay back really neatly around the sides.
The last thing you want to have
is liner hanging out it just looks blatantly obvious that you've
lined it. Obviously all of these stones
are cemented in so they're not going to go anywhere
safe to walk on and climb over.
All the stones in the rockery aren't cemented in they're just
Dug into the ground.
When you look at the path of the water coming down
the cascade you can see by the bubbles it flows
right along this back edge in the shallows.
It's exactly what it wants to do. The pump's sitting in
this deep end here moving water into the filter back down the cascade
and it's arriving right at
the far end of the pond so the water has to travel all
the way from here to here before it gets pushed
back into the filter and down the cascade which is great.
We have left enough pipe on the pump
To be able to move the pump from here to here
in the winter by having the pump in the shallow end
where the cascade pours in means it'll keep
the filter alive in the winter but won't disturb
the main body of water where the fish will be hibernating.
The filter that we've used in this
job is from a German company called Oase.
They make very good pumps and filters. We've also
And this filter is a filter clear 13000.
probably is a little bit too big for this pond
but there is going to be koi going in here
from the lady's previous pond
so i always like to go slightly over on the filtration there's an
integrated 55 watt uv runs right down the middle of here
and what happens with this is the water
comes in here from the pond it flows around
and around the uv which kills the algae kills
bacteria pathogens parasites and so on and then it flows through
a series of foams in the buried part
This is probably about two foot,
two foot six deep in the ground, foams, water goes through the
foams out this pipe up to the cascade.
There is another fitting here which allows you to attach
a pipe which can then lead to a drain and when you
want to clean the filter all you do is turn that,
point towards the drain leaving the pump on,
take the handle pump it up and down
And what that does, it actually washes the foams out
in your pond water, removing all the muck to the drain.
It means that you don't have to pull this
apart and you don't get your hands mucky.
Once you've finished the cleaning process,
all you do is just turn the valve back here, put your cap back on.
Really simple to clean.
This is the pump that I'm using.
It's an Aquamax Eco 8000 from Oase.
Heavy duty pipe.
It means it's not going to crack.
It's very hard to pierce and it's going to last a hell of a long time.
The pump itself has got a five year guarantee,
so it's going to last well.
The last thing I want to do is come back to a job
because of a faulty pump or something
getting blocked or some sort of problem that could have been avoided.
This particular pump actually has two inlets.
It's got the obvious one through all
these holes here in the cage, but it's also got
one here as well.
By taking this off and attaching a hose tail
and an extra bit of pipe, you can have it
either go into a skimmer to suck all the muck off the top of the pond.
or you can have it go into a smaller version of this cage
which is called a satellite strainer
which means that you could pull from two different places in the pond
so you could pull from the deep end and the shallow end simultaneously
so really the key to a successful pond
is obviously creating it the right size for the fish
you're going to stock and also having a good pump
which acts as the heart of your pond a bit like
the heart in your chest instead
of pumping blood around it's pumping water around and also a good
Think of this as the lungs of your pond
this will filter out all the muck your pump pumps into here
and hopefully you should have crystal clear water.
Obviously the pond at present hasn't
got crystal clear water we've only just filled it up
and we've been working around it with
mucky soil but I'll do an update
when I come back and sort the bank side out
and it should be crystal clear then.
That's it for this series of videos
We've switched the cascade off now.
The cement's only been in there a couple of days,
so we had it running before just to test that everything was okay.
It is, which is always a
bonus. And we're going to leave that to go off
for at least a week before we set it away proper.
Thanks for watching this series.

I think I got it near enough the first time.
Simultaneously.
Still got it wrong, didn't I?
Simultaneously.
Is that right?
Is it not sum?
Simultaneously.
Ah, that's one.
Simultaneously.

What the f***?
Prova.
Prova.
We want to start a footwork because we have to.
What can I do when people are watching this?
I'm
starting
to
speak
now.
