Koi Pond Construction

There is probabley a better group somewhere but I might aswell start here. I want to build quite a large pond, about 25ftx25ft which is 2 or 3 times the size of even a normal large pond. I am going to build this abroad where I have plenty of space and construction costs are not an issue. As it is going to be larger than average and if I keep the stocking level the same ie a much lower density, can I assume that I can get away with a proportionately smaller filter. Could I get away with 5 bottom drains or would I need more. As I said, I will have a reduced stocking level because of the increased size.

Well for a start that is a massive pond if it is going to be a prope depth - say 6 feet +? If the bottom is rounded so that there is no fla bottom or right angle edges then two bottom drains should be enough a all the muck will tend to fall to the lowest point/s. I would never skimp on filtration as it is difficult to increase i once you have designed and installed a system so you cant have too muc in my view.It is probably going to be difficult to keep low stockin levels unless you do not buy any more fish or cull the new ones ever year. Also the existing stock will grow fast in a big pond. Also dont forget that they will be hard to catch in a 25 foot pond! A good site which i used to use is madaboutkoi.com or koi cymru.

Good luck

I accept the bit about catching them, once they are in there they will be in there for good. The reason that I ask about numbers of bottom drains is that I will have to take them with me on holiday on the plane so with one already there and two holidays a year taking a couple each time I would limit them to 5. I know that the recommended size of filter is 1/3 of the pond area but even if I cut back to1/4 that will still be a huge filter. I guess that at the end of the day I will build as big as is practical and looks right at the time of construction.

Read up and take advice. The BS about filter size being 1/3 of pon size does not add up at all. Think about it. It all depends on how man fish and how much water NOT surface area.Also how much food is put int the pond. Go to a good website and read everything. Dont waste your money.

A big puddle of green slimey water and dead fish is just not worth th gamble. I assume you are going to a "hot" country (Spain per chance?) and a you know warm water holds less oxygen than cold water so your stockin level is immediately compromised.

Do it right as you have the chance
