I just found the answer in a two second google search- safe for fish. 160 gallons is far too small for koi. What are the dimensions? What filtration do you have?

Hi acamp,

As Cheri has already pointed out, that pond is far too small for koi. Would it be possible for you to increase the size of your pond?

I have three koi. The first is 2 inches the second 5 the third 6. I will build a pond at least five times the size next year. I have a UV filster for 640 gallons and a pump for 800 gallons. I think im doing quite good thank you vey much.

May I ask why you didn't build a 600 gallon pond to begin with?
It would have just been easier for you, rather than having to build two ponds

Hi acamp,

I really wasn't too sure on the thinking of starting off with a smaller pond, seeing how it goes and then building a bigger pond. It doesn't make any sense to me, to build something that's too small for a fish and see how it goes, when it's not going to go well if they do not have their basic requirements met in the first place.

Now I know a lot of us here don't have koi, so I got in touch with someone on another forum I belong to who does, because I personally don't know much about koi to be giving any advice.
Andy T (a.k.a Koinut) who I contacted is one of the forum's moderators and is also a Koi and Pond Specialist, so he knows what his talking about

First he gave me a link to this really useful thread- (Link is not visible to guests. Please register to view.)
It has all the basics you need to know about Koi 

The second post underneath it is some information written by Dr Paula Reynolds (BSc PhD BA) who owns Licolnshire Fish Health, the information is with particular regards to keeping koi in small volumes of water.

From Andy's message, he told me the 160 gallon pond is too small, even now and a 600 gallon pond, still won't be big enough, the reason for this, is pretty much summed up with what he told me about koi growth-

"A lot of Koi will reach a foot long in their first year..this is not at all uncommon and they grow quickly in the first few years.
I have 4 year old Koi that are well over 2 and a half feet long."

I know this is a lot of information to take on board, so please take your time to read and understand it.
If you have any more questions then please ask and I will do my best to get the answers 

I guess... it's a nice idea, but again, the lack of research is going to be a problem

Really, parents don't always know best. Oh, how about going back to the shop with the koi and buying a few common goldfish instead? They would do great in a pond of this size! You could even keep 5-6 goldfish happy there...

I live in the South and there was only one day where the temperature was below freezing. and Skwishee go build a pond and buy some koi then you can start critizing me. Furthermore I was just looking for some simple advice and not half the forum hating on me. So please if you have something mean to say tell your mom or someting.

Why do you ask for advice when you intend to ignore it?

Ok, sorry for overreacting. And yes Nossie i have a UV filter for up to 640 gallons.

Thank you for your concern of my fish and I am very grateful for it. Can you pass on Koinut's email to me please. Could you please send it to me by private message. Thank you for you time and for caring about me and the well being of my fish Skwishee. 

ok it is ************.com im leaving it on for 2 hours. Thank you skwishee

Ok thanks.
