    Ok. Do any of you know how many gallons an 8 by ten liner would be?

    Well an 8x10 pond with an average depth of about 2 feet would be around 1200 gallons. But an 8x10 liner doesn't translate to an 8x10 pond, since you have to account for depth as well as width and length.

    And in a pond stocked with fish, you have two types of filtration - mechanical and biological. Many people use some type of skimmer to catch large debris off the surface of the pond. A pre-filter on a pump is another for of debris catcher.

    A biological filter relies on, well, biology - bacteria and plants - to remove the excess nutrients from the water. A biofalls or a bog filter are two types of biological filtration. There are other more complex systems that I know nothing about - maybe someone else will chime in with those.

    As Lisa said If you go with a 2’ deep pond that would reduce your liner to a 6’x4’ pond but you need at least another 12” to allow for rocks to hide liner and berm up the sides.... I would go with a bigger liner because you will not be able to keep much in a pond built out of an 8’x10’ liner.

    NO KOI! haha! You wouldn't want koi in a pond that was under 1000 gallons, and even then that would be great for like one!

    You could have common goldfish, sarassa comets, shubunkins, fantails, or a combination of several kinds. They are all goldfish, just different varieties. Just remember that they breed like crazy - start with a three or four and you'll soon have a pond full.

    Thanks guys! I'll use filter media for my box filter, quite literally a box with a filter connected to my pump.

    Hi Pondguy3579. Welcome! It sounds like you are pretty ambitious about keeping a nice array of fish. I would recommend starting out with less fish than you think the pond will hold and see how that goes. As you get pretty confident maintaining your pond you can always add more fish. Have you learned about how to "cycle" a pond? There is actually a lot to know about keeping healthy water for your fish so as to keep a disease free pond and new ponds are much more work than ponds with established "good" bacteria colonies.. It's much easier to start slow than to start out with too much bio-load and have to deal with ammonia spikes and sick fish. It can be a real lot of work and is always sad when fish die when they didn't have to. Remember that pond fish can grow fairly large and have babies so even if you start with just a few fish it will not necessarily stay that way. I have about 70 fish in my pond and most of them were born in the pond. Good luck!

    I have kept koi for 30 years now 22 of those years indoors in a large 6 x 2 x 2.5 aquarium but doing it that way is very labour intensive and you had to be on top of things 24/7 365 days a year at least with a pond its less labour intensive , however koi produce large amounts of poop you would need a filter that would be man enough to take on the koi but I would suggest you didn't go down that route .
    If you want to keep koi at a later date learn your craft using goldfish as a start then when you can build a pond of 1,000 gallons upwards then start keeping koi

    Okay, so I start off with three or four, then slowly add two every month or so. And I've heard that you have to let a pond cycle for three weeks

    Thats actually really cheap considering what professionals pond keepers use for there koi
    Anyways a well prepared DIY filter can be even better than bought ones.
    What do you plan to use for media?

    That's the same one I run in conjunction with my DIY filter. it's actuall pretty cheap. Unfortunately, there isn't much that is cheap when it comes to ponds if you want to do it the right way to avoid future headaches.

    If this is your first pond/aquatic environment setup (which it sounds like it is), then you need to learn how to test and monitor water quality.
    Fish should be the last thing you add to a pond.
    For monitoring water quality, you can use an API master test kit, be sure and also purchase (and use) a KH/GH test kit. Do not add any fish until you have an established bacteria population.

    Fishless cycling is the most humane method to cycle a pond using ammonia.

    We would hate to see someone rush into a pond setup only to have them be frustrated with fish deaths or nuisance algae problems.

    Keep asking any questions you may have, No question is too basic.
