Recreation swim koi pond DIY build 6,000 gallons (expanding old 1000 gal koi pond)

Recreation Swim Pond (also called an organic pool): - 6000 gallons - overall size: ~ 20 feet x 20 feet - shallow end depth (old koi fish pond): 18 inches - swimming pond depth (new pond extension): 4.5 feet Took us about 3 1/2 weeks to build it and it cost approximately $2K in materials so it's very doable on a small budget. And yes, we do still keep koi fish (some goldfish & golden orfes also) about 30 of them in total from 2" to 12" in size and of course we swim with them: https://youtu.be/NfEDIlvCypM Parts & materials list: Best work gloves: https://amzn.to/3TUKpE7 Backyard hanging lights: https://amzn.to/33JlZCR LED RGB Smart Lights (2 sets): Novostella 2 Pack 20W Smart LED Flood Lights, RGBCW https://amzn.to/3bfLekc Wavemaker (to keep the water moving and circulating): https://amzn.to/2T1VOFd Patio chairs: https://amzn.to/33vbtih Waterfall attached to the deck: https://www.amazon.com/gp/product/B000P6B5L2/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B000P6B5L2&linkCode=as2&tag=redscapes0a-20&linkId=b2b70633a262e84b2030e2b99251c836 Or if you want a smaller version (this is the one we used on the forest side waterfall): https://www.amazon.com/gp/product/B00VBP5TQS/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00VBP5TQS&linkCode=as2&tag=redscapes0a-20&linkId=7e2a2facd070ab186906658bd6320a23 Or something like this if you'd like to go in between the 2 sized we used: https://www.amazon.com/gp/product/B0018CDT3E/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B0018CDT3E&linkCode=as2&tag=redscapes0a-20&linkId=f009ec8c45b7ea53bb031cef0b6b7fcd Deck waterfall pump (need powerful pump to push wide water blade through above linked waterfall): https://www.amazon.com/gp/product/B07THX1DZ1/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B07THX1DZ1&linkCode=as2&tag=redscapes0a-20&linkId=8b6d756563f7960a4a966ce7bc38c46c Canister filters (2) (on the deck waterfall and the stone waterfall) https://www.amazon.com/gp/product/B07YKGZG4P/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B07YKGZG4P&linkCode=as2&tag=redscapes0a-20&linkId=06af543739b2247466ce3de8751f76b1 Pumps (2) feeding the stone waterfall and the bowl waterfall: https://www.amazon.com/gp/product/B0049XENYS/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B0049XENYS&linkCode=as2&tag=redscapes0a-20&linkId=9427e4f2c9ddefbfd481e115f1356a08 Skimmers (2) https://www.amazon.com/gp/product/B002RBCT0O/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B002RBCT0O&linkCode=as2&tag=redscapes0a-20&linkId=b9b10ad74494f5fd24daf3b213476db5 Liner: 20' x 30' https://www.amazon.com/gp/product/B005BY5ZC8/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B005BY5ZC8&linkCode=as2&tag=redscapes0a-20&linkId=1fd7c815089ed6ee4dd40a375454b8ca Other sizes: 10' x 10' liner: https://www.amazon.com/gp/product/B005BY611C/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B005BY611C&linkCode=as2&tag=redscapes0a-20&linkId=9d5b123ea3bfe6d58a710efd30242c65 10' x 15' liner: https://www.amazon.com/gp/product/B005BY613U/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B005BY613U&linkCode=as2&tag=redscapes0a-20&linkId=6b08898ddbe91ee1d4cb3356cb596dad 12' x 15' liner: https://www.amazon.com/gp/product/B005BY5XJI/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B005BY5XJI&linkCode=as2&tag=redscapes0a-20&linkId=9fb173971d5ebabbbe21b7975f69682d 10' x 25' liner: https://www.amazon.com/gp/product/B002IUPTEC/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B002IUPTEC&linkCode=as2&tag=redscapes0a-20&linkId=97ad3d05f249362127f1719e5d85c701 15' x 20' liner: https://www.amazon.com/gp/product/B002IUPTDS/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B002IUPTDS&linkCode=as2&tag=redscapes0a-20&linkId=e73298e1d1a0d123446a4364b9f00978 20' x 25' liner https://www.amazon.com/gp/product/B0012SM2QE/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B0012SM2QE&linkCode=as2&tag=redscapes0a-20&linkId=1551f8b527e0ae6a6a53cfd17ba12180 Liner seam tapes (to attach old pond liner to new. you need both for a good bond that lasts) 3" Double sided: https://www.amazon.com/gp/product/B00069UDKW/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00069UDKW&linkCode=as2&tag=redscapes0a-20&linkId=b0d629ff45a518e82bdeaabfbc374197 6" One sided cover tape: https://www.amazon.com/gp/product/B013PCI5R4/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B013PCI5R4&linkCode=as2&tag=redscapes0a-20&linkId=bb2e3a51341cc52bff72273b286b34a5 Liner tape primer (needed to get a good bond that lasts): https://www.amazon.com/gp/product/B00CEHP9AS/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00CEHP9AS&linkCode=as2&tag=redscapes0a-20&linkId=d1bda7ff3e2e33ecdfb7392adcb9d4bb Flexible Tubing: https://amzn.to/3y2mndx
