    There are basically three types of ponds that people generally build:


    PLANT PONDS - ponds designed for plants only, no fish. Usually
    built by avid gardeners who want to try growing new types of plants.
    These pond have little or no circulation and filtration


    WATER GARDENS - Ponds designed for a combination of plants and
    fish. This is the type most people picture when they think of ponds,
    moderate size and depth.


    KOI PONDS- ponds designed for only koi, no plants. Usually,
    serious aquarist build these ponds (it is much easier than building a
    10,000 gallon aquarium). these ponds are designed larder and deeper than
    most water gardens and have large filtration systems.

    Good description. My koi pond was built with its own veggie filter built in so no
    need for large filtration. It is also built so koi can be protected from predators.

    When you are designing the pond, make sure you consider the technical
    aspects, not just the design features and pretty modules.

    I spend about a year working on the weirs trying to get the water flows
    balanced. (Two from top pond into the middle, one from the middle into
    the lower pond and then one into the pump chamber, and

    When I built my pond and associated bog garden a couple of years ago
    (started as your first type, but then got some goldfish and it became
    your second), the one mistake I made was to have the shelf around the
    edge too deep for the marginal plants (~15 in. rather than the ~9 in.
    it should have been), which meant I had to stand all the pots on bags
    of grit to raise them up or else they would have been too deep.

    Here's an approximate section through my pond (excuse the ASCII art).
    10 ft, one third of which is the bog garden. Maximum depth about 3 ft.
    No pumps, no filters, no feeding the goldfish. Plants are water lilies
    and irises mostly, with candelabra primulas, irises and calla lilies
    in the bog garden.

  5. How many goldfish, Chris? Are they multiplying for you?

    Our pond is in the second category in the main pond is 2' deep and
    about 2,900 gal. It is, however also functioning as a koi pond...tho'
    not at the 10,000 gal level! The koi seem happy with it and have
    grown large. The berm ponds are veggie filters and hold another 1,000

    My pond is about 1650 UK gallons (say about 2000 US gallons), by
    calculation not by measurement. No berm pond or filters. There are
    some 15 - 20 goldfish in it, introduced as fry say about an inch to
    inch-and-a-half long, about 20 months ago, given to me by a neighbour
    whose goldfish breed prolifically. They're now in the range 3 - 5 in
    long. Some have turned 'gold' (orange actually), others are still dark
    brown or dark brown with gold spots or flecks. There are a couple of
    very pale pinkish-white ones. A gold one got rather fat last autumn, I
    assume full of eggs, but with the onset of winter nothing seemed to
    come of it, and no sign of anything this year. But as I don't feed
    them, they eat almost everything that moves, including any newly
    hatched fry, I suspect. I don't actually want or need any more anyway.
