It's finally happening!

[The Masked Shadow]

My parents are funding me for digging a koi pond. I've been planning this for 2 years, and my parents are finally doing it! The pond will be around 2,000+ gallons and an oval. It will lead into a stream that carries water 10ft down into a 500-700g pond. Then, a pipe will carry the water back around 20ft or so, and pump back into the large pond. My parents have a budget, so I think pond liner will be the best.

So I have some questions

What is the best filtration for it? **No other water feature than the stream**
Do you think pond liner is fine for it?
What is the best way to build the stream?
What fish can live with koi?

Congratulations! I’ve always wanted a koi pond!
I have no answers to any of your questions besides suggesting other coldwater options like bullhead cat or rosy minnows.

Big one will be koi and the other will be natives (i hope)

You will hate yourself for using pond liner. No matter careful that you think you are, it will 100% get a puncture and leak.

Maybe you can own monster fish now ??

I'll do a double layer.

I'll do a double layer.

To double your chances of getting a leak?

Is there something that is cheap that I could use besides cement, rebar, or PVC?

Could dig it out and try building a wooden frame to put inside the hole and double layer pond liner. Not sure
