How to build a garden pond
These pictures are the steps I took when building my pond in my garden. The old small pond was having serious algae issues, so I decided to go big on proper filtration.
The Filter I ended up with was a 11000 litre/hour Bio mechanical pressurized unit with built in UV clarifier, I also bought a 5000 litre/hour pump with all the spare capacity I made the decision to dig out and extend my Pond and also add a waterfall and fountain.
The original pond was raised and formed a bit of a sitting area so the route for me was to continue this theme all the way round.
Once all the digging and shaping was complete a concrete foundation was poured into the shuttering that was supported by the bricks. Once the concrete was set, it was time to get the trowel out and the trusty spirit level and the brickwork was completed using a mix of 4 to 1 (sand to cement).
The underlay is one of the most important things to consider, it is the done thing to get hold of some old carpet, this is both very strong and very tough and is ideal. I went to a carpet shop and asked what they did with the carpets that they remove when laying new ones they told me to help myself to whats in their skip….yay!!!….result.
So with the entire pond now trimmed with carpet its time to install the liner.
Best tip here is to take your time, and slowly fill with water, gently pulling away any crease. That done, its now just a simple matter of completing the brickwork and cutting and cementing down the toppings.
A good clean down and with the pump and filters working all will be good.
finally I can actually see my fish.
The whole project was completed in one week and my pond now measures 4.5 metres by 2.5 metres and can be filled to a depth of 800mm.
The fountain is presently fitted with a Mushroom head, and the waterfall was custom made and make a really great sound. BLISS….haha

very good brick work. how large is it? im currently building a large(10,000 gal) koi pond. all dug by hand as well, tree roots. lol. but, will be worth it when the liner is in it. i got a few vids of the progress. liner is spendy when you need a big one too. damn.
hello, I took a …
hello, I took a look at you pond on your video, and it looks really cool. The digging is a back breaker isnt it ?
Ive found that the Algae can be controlled well if you clean out your filter once a week. but its really all down to your UV system, and the capacity of the filter. The UV lamp will make the green water Algae stick together and form bigger lumps and this is how your filter will catch it. basically if your pond is 3000ltres, go for a 10000 ltr pump and 25w UV lamp..hope this helps
Thanks for the …

I’d like to offer a suggestion. If you got one of those filters with a UV lamp that kills those green algae it would stay nicer looking….just a thought. NICE JOB!

I loved how you …
I loved how you built it but I am wondering why you let so much of the pond liner show and don’t fill it deeper?
If you could let me …
If you could let me know what size and depth you would like and what type of pond ie. ground level or above ground, then I will work out what you need in also work out the correct filter and pump size..:)
