Setting up a pond
Hello! I'm a new member here and I'll be setting up a small above-ground garden pond.

The structure has been built already. It was a concrete structure surrounding a tree in our backyard but a storm blew and a lightning strike split the tree in half, killing it. My folks and I decided to make the concrete structure a pond, so we raised the walls a little bit and waterproofed the inside. It now measures 5x5x2 feet (planned water depth, not structure height) with a small island in the middle, where we will be placing a potted plant to provide the fishies with shade.

I plan to add water plants and some goldfish and probably, one or two koi.

I've seen koi and goldfish coexist peacefully so I plan to mix them. (If you have experience otherwise, please tell me). I would've put only koi if the pond weren't too small. I love koi, especially kohakus (as evidenced by my avatar)

So, how many fish can you recommend putting in?

And btw, I will be having filtration by means of a pump and a DIY bucket filter.

So, those are the basics of my project. If there's any aspect of it you would like to know, please do so, so I can post it and for people to hopefully correct it if I'm doing it wrong.

I need to know how many gallons

adiumroot 04-13-2009 01:37 PM

I used an online calculator and it says 311.5 UK gallons and 374.1 US gallons. Take away a bit about 10 or 20 gallons because there's a small island in the center.

im far from pro on the goldfish/koi and even ponds but my father has "baby sat" his friends 2 koi and temp. put them into his fancy goldfish tank. one of the goldies is now missing an eye because of the koi.

i have also seen koi 3'+ that were 30 years old. plan for the long term and goodluck. welcome to the forum.

In all honesty, that amount of gallons is not sufficient enough for just one koi. A full grown koi, from what I have read, need at least 500 to 1000 gallons for just one.

You have to consider the swimming space, the amount of oxygen a large koi is going to use for itself, and the huge bioload amount one koi is going to put off.

Now I am not saying that you cannot put any koi into it temporarily. I am just saying that you need to have a back up plan because koi grow quite fast, and I am sure the last thing you want to do is stunt their growth. I myself have 12 5 inch koi in a 200 gallon above ground pond that I am growing out. But I have a 20,000 gallon pond for my big uns.

I hope you enjoy your time in koi keeping. They are very enjoyable and quite rewarding when kept properly.

So I guess I'm sticking to goldfish then, since they don't grow as big as koi. Thanks guys. I'll update this thread once I get it set up.

Goldfish would be perfect, and will never outgrow that pond. :-D

looking forward to pictures.

I have another concern, now that the pond is almost done...

What kind of paint should I use and what color is good for painting the interior of the pond? I know there are specialized pond paints but I don't think they are available locally and getting it shipped in is gonna cost a lot. Are there any other alternatives? Roof paints, perhaps?

adiumroot 04-17-2009 12:29 PM

Okay, I decided to not paint the interior anymore. Not my decision actually, but my folks'.

I've now added a few plants, installed the powerhead and filter, aged the water, and now, I've started cycling the pond with 4 black mollies in it. I really think I should've bought more since 4 small fish are going to produce very little waste compared to the total water volume.

I just noticed that there are tiny leaks in the sides! Well, it's not much but it would be a problem in the long run. I don't think it would deplete the water level significantly, so I'll be waiting until morning to fix it (noticed leaks at around midnight)
