      Midwest

      So I've been following this site, researching on and off for a couple years. I was all set to dive into my first ever Koi Pond this summer (we are in the middle of winter) but then came across the post from Auntiesue called BIG MISTAKE.

      So now I have a big concern that I'm not ready or it will be much more costly than I expect. I wasn't planning to use concrete as I'm not on a huge budget. So I was going to purchase some of the items needed like an aerated BD and Skimmer but planned on DIY bio filtration systems. We have had reef tanks for years and want to take the dive into a kio pond as we love having fish and find them so beautiful.

      Anyone from the Midwest that has tips, advice, experience that they'd like to pass along on how they supported, or maybe didn't support their sides.

      My plan is a 10x10 being 5-6ft deep.

      Thank you so very much

      We are you located? If you are close to the Twin Cities area, you can come to the Upper Midwest Koi Club activities in the summer time. I have a 8'x12' 5-6 ft deep semi-raised pond so similar to the one you plan to build. If you make a footer, put concrete blocks on top and then EPDM liner, they are not expensive at all. Menards also carry bond beam blocks which you can put rebars on them. Depending on what you plan for the filtration items, they could be expensive.

      I'm located in Circle Pines. I really appreciate your response. Is it a must to have concrete blocks or some sort of side support so the sides don't cave in because of our weather conditions?

      Again just reading that post called BIG MISTAKE and now it has me questioning.

      Sounds like a great idea for me to swing to those activities. I just liked the FB page!!!

      Sue made the mistake of digging deep straight walls on a hillside so the runoff after storms/lawn watering ran behind the liner.

      Thank you so much for this. So as long as I'm on flat ground, and have my sides gradually come to the deepest part in the center, I should be good?
      Something along the lines of this for slopes but with a 3-4 inch aerated BD.Name:  Screenshot 2023-01-22 115604.png

      You don't need to use cinder blocks below grade. People do that so that they can have straight walls below grade. Many people advocate that because the straight walls will minimize bird problems and maximize your pond volume. I personally is never comfortable for straight walls ponds because I believe that kind of ponds pose bigger risks for children and even adults. To avoid cave-in issues, put a concrete footer even though you don't plan to put blocks above it. You will also need to slope the walls below grade but don't put any plant shelfs to minimize bird problems. You also need to think about how to winterize the pond for winter. I highly recommend you design-in your pond with flow through and overflow systems and you will find them very useful to maintain water quality and grow koi.

      Koi Aces - Thanks for that info

      My plan is to have my sides gradually slope in to the deepest part in the middle of 5 ft where I plan to have a 4 inch aerated bottom drain. No plans to put plant shelves in. Really looking to keep this pretty simple.

      Is it a must so have side support if I won't have straight walls?

      I do have a lot more studying to do when it comes to correctly winterizing everything. I will look into flow and an overflow system....THANKS

      The edge of the pond may cave-in as the soil is likely unable to support your weight when you step on it. Depending on the soil type, you maybe able to get by with a layer of cinder block.

      Do you think if I have a gradual slope like the photo and go 5 ft deep I'll run into caving issues here in MN?Name:  20230122_222318.jpg

      Would running 1 ft concrete collar prevent sides caving in? Name:  20230122_223316.jpg

      Oh I forgot to mention, I'm no handy man that's for sure so learning and studying as I go. As much as the family would love to have a Koi pond, first we have to make sure we don't break the bank

      Proper pond side wall slope for your soil type in MN is the best long term - no cave in/sloughing - for a build in MN

      Soil types vary drastically and so do its ability hold in place. Only an evaluation on site can one make an educated guess what structure and slope are needed. Hand dig a test hole. Note surface layer thickness, depth and structure. Once into subsoil evaluate its ability to hold together. Note surface conditions after heavy rains. Don't underestimate Mother Natures ability to deconstruct what you construct.

      Check out ThePondDigger's Koi Pond Construction videos on YouTube. They provide a lot of detailed information.

      I documented my build here on Koiphen. Maybe it will help give you some ideas. Since my build, I upgraded the bead filter, installed a second settlement chamber and installed a large bakki shower I found here in the classifieds. But the initial system worked great and it was on a pretty tight budget. I just wanted to add more fish.

      I'm no super expert, but will chime in when I can. Good luck!
