This video shows how i built a natural looking fish pond in my backyard for native fish. It has a DIY skimmer, biological filter and stream. The fish are Southern pygmy perch and Murray river rainbow fish. These fish are native to SouthEast Australia.

I was quoted between 10 and 16 thousand dollars. I couldn't afford that so i built it myself for just over $2000. This is Australian dollars, everything is a little more expensive here.

I think this is everything you need to build yourself a pond like this. Most of these links will be amazon links as a member of their affiliate program if you do make a purchase i will receive a commission. This costs you no extra. You can also just use the links to help see what the components look like or roughly how much they cost.

Geo textile underlayment https://amzn.to/3jBoG1U (X2 if you want to sandwich the liner between to layers).

Firestone EPDM Rubber liner https://amzn.to/3yQUrIR

Used Olive barrel for the Bog filter https://mgplastics.com.au/plasticbar... (this is an Australian company but you'll find these types of containers second hand anywhere in the world.)

Uniseals to create watertight holes in the barrel. You need 2 one for the clean out and one for the overflow. https://amzn.to/2WOtdp7

2" PVC pipe for overflow and clean out https://amzn.to/2Vfhuzc

2" PVC Ball valve for clean out. https://amzn.to/2Yo8sB9

2" PVC 90 degree elbow https://amzn.to/3zJzS21 (attach to the overflow so water in directed down instead of jetting out into the stream. You might also like to get another to help lift water off the very bottom on the clean out pipe.)

PVC Glue https://amzn.to/3Bz38Jt

Flexible 1 1/4" PVC pipe. https://amzn.to/3mXPZFD ( To move water from the pump to the filter) 25ft should be enough but it will depend on where you position the skimmer in relation to the bog filter.

1 1/4" PVC 90 degree Elbow X 2 https://amzn.to/3jFpR0r To help connect pump to the flex pvc and filter barrel.

1 1/4" PVC pipe rigid https://amzn.to/3teHDe6 (this is cut to the length required of the barrel. This is the pipe that runs from top to bottom inside the bog filter barrel)

1 1/4" PVC t piece fittings https://amzn.to/2WOxeKd (To help disperse the water at the base of the filter.)

Bucket to create skimmer https://amzn.to/3BI3bmp (Doest matter what type of bucket or container as long as it can fit the pump you choose)

Submersible pond pump Low volt DC https://amzn.to/3yKtTbY (This is a different pump to what i used in this pond, however i used 4 of these pumps on my dream pond build and have been really happy) The transformers need to be kept indoors or protected from weather. They can easily be extended if need be. This video will help if you need to extend the low volt DC cable    • Plumbing bog filter| Wiring low volt ...  . If you wish to find another alternative anything that delivers around 1000 1200 gallons per hour will work fine.

Matala filter mat https://amzn.to/3mXVEeR (Cut to size to sit over the pump in the bucket)

Waterfall foam https://amzn.to/3BBp46D (To seal cracks and crevices when creating the stream. Can also be used to seal gaps in the rocks used to create the skimmer)

Pond flocculent https://amzn.to/2WOBSYF (To clear up muddy or cloudy water)

Beneficial bacteria https://amzn.to/3mXXOet (Beneficial bacteria to kick start the ecosystem)

I think that's it for all the plumbing, pumps , underlayment and liner. Now you just need the rocks and gravel. I also have a downloadable pdf that includes the formulas I use when building an ecosystem pond https://ozponds.com/pondequipment/
