Winterizing Pond For Koi

My pond is intex pool that is 3,5 feet deep.and it is bare bottom but I read that koi burries in mud so should I have mud in pond for koi or is it not needed
Ps if somebody knows good oxygenating plant and floating plant that can overwinter please let me know

 

I don't have a pond myself, but I know someone who does. I've never heard of koi burying themselves, I don't think that adding substrate is necessary. Generally, ponds over 2.5 feet deep won't freeze over, so you should be good there. Some people bring the fish in over the winter, I don't know if you would have to. Some good oxygenating plants may be parrots feather, and anacharis may do well.

 

What about hornwort or water hyatchin

 

I have no experience with water hyacinth, it's illegal where I am, and I think hornwort is good down to about 45-50°, so it'll probably be fine.

 

Ok thanks

 

Hello!
I'm planning a goldfish pond. It'll be around 2 feet deep. It doesn't get overly cold in winter, it gets around 3 degrees Celsius (37 Fahrenheit) minimum over winter, never ever snows and only the occasional frost but never enough to freeze any part of the pond.
Would the goldfish be fine over winter? Or is it too cold? Thanks!

 

I think you should have made it 3 feet deep in one part if not allof it but that's just my opinion

 

Sounds like the goldfish will be fine!!! It gets down to 0 degrees where I live and I am planning on letting my Goldie's out over winter!!!

Ok. I’ll remember that for the future. It’s a bit late now though.

Thanks!! It's 300 gallons!!

 

So that's around 1135 litres. Pretty big for a pre-formed pond.
