    I like the way you have dug out your pond. Eliminating the middle bench makes for more water volume and more room for the fish! I love it! Our clients LOVE the fish cave installation. I have so many testimonials from clients saying without the cave the HERON would have cleaned their pond out! If you can, ADD THE CAVE DURING EXCAVATION!

  • @Soper79
    @Soper79 11 лет назад

    And I should mention I never heard of or seen the fish cave demonstrated until you had it in a video sometime back in one of your older demonstrations. A great idea and I'm a full believer in it. You do great work. Thx for all the tips.

  • @ThePondDigger
    @ThePondDigger  11 лет назад +1

    Great suggestion! We do this in most of our installs! This video series was slow to come together but FAST in the same regard. We missed this step in the instructions! Guess that means we will need to move into another video presentation so we can teach more great tips and tricks. Thanks for the comment!

  • @ThePondDigger
    @ThePondDigger  11 лет назад +1

    We dry stack and backfill the rocks we are installing in the pond and then we lock them all together with expanding waterfall foam. They are not as stable as concrete but done correctly you will have very stable rock work.

  • @ThePondDigger
    @ThePondDigger  11 лет назад

    The granite we are using is plentiful in our region and is considered a river rock as well. I would definitely suggest looking for a local rock source to keep your project in budget. Bringing in rock from other states can cost quite a bit of money because of trucking. If you are purchasing the stone from a local rock yard tell the sales rep you are building a fish pond and ask him what kind of rock the local pond pros are using for installations.

  • @ThePondDigger
    @ThePondDigger  11 лет назад

    We are purchasing rock from our local quarry and or rock yards. Some of the local DIYer's do collect rock for their pond.

    Would it be okay to leave the bottom and sides empty in a huge pond? what would you recommend for it? there is no way I could buy that much rock for suck a big pond.

  • @ThePondDigger
    @ThePondDigger  11 лет назад

    EXACTLY!! Thanks for your reply!

  • @Soper79
    @Soper79 11 лет назад

    Good tip. All along this series I was wondering what you would do with that steep wall to keep the rocks from eventually falling down. I like the use of small rocks & waterfall foam sealant to lock those in place. Almost like you're mortaring them solid. A good tip. I'll remember that, thanks. Otherwise, if you keep doing 8 inches down, 8 inches down for every level, you need a big footprint for the size of your pond if you want a deep pond. Plus that'd be uniform which we don't want.

  • @ThePondDigger
    @ThePondDigger  11 лет назад

    On this pond we will use approximately 6 to 7 tons of rock because we will be using several large stones around the pond, skimmer, exterior edges and in the waterfall.

  • @Jamestrus1
    @Jamestrus1 Год назад

    I've watched your entire series her. It's so informative. You've illustrated so many problem areas. So great!
    I'm renovating our pond that was here when we moved in 21 years ago. I've emptied it totally to 2" water in the bottom (3rd time in 20 years) It's 52" deep and app. 48" to 62" kidney shaped.. I have varying benches around 2 walls at app. 6' - 8" from the top. The walls go straight down to the bottom.
    Do I absolutely need to rock the walls from the bottom? It wasn't originally. Do you have any suggestions or tips I could follow for my best solution?
    Could I text you a photo?

  • @ThePondDigger
    @ThePondDigger  11 лет назад

    Rock through out the pond is not completely necessary. Consider not doing such vertical tall walls on the dig because we use the rock to support the excavation. If you do smaller 8" steps then your excavation will be fine. FUN FACT: The UV from the Sun is no longer damaging at 36" deep. Be sure to use pond liner that is UV tolerant if you plan on leaving the liner exposed to the sun. Good Luck!

    Great demos, Eric! On an 8'x11' pond, how long should a do-it-yourselfer expect to spend on rocking in a pond? Assume a maximum of three workers who aren't as experienced in selecting/placing rocks like your team.

  • @losangelessecuritycameras
    @losangelessecuritycameras 7 лет назад

    Hi Eric, what happens if you loaded all of your rocks in the pond and later you discover that there is a leak? How would you find it? ALSO, I noticed that you didn't put a second liner below, do you recommend a liner below and if so, which type of liner?
    Thanks again, your videos are AWESOME!

  • @ThePondDigger
    @ThePondDigger  11 лет назад

    Roughly 6 to 8 tons. Wait till you see the size of the monster rocks we wrestle into the waterfall by hand.

    My first pond I made was a smallish I'd say 7x8 pond and only 2 levels deep. Probably a max of 24 inches deep. There's a funny saying that goes "Anything less than 8x8 is a dinner plate" :P Anyways, that pond would routinely get raided by raccoons in the summer. One night saw a family of 5 of them. After that, I would always recommend a fish cave. That and get some good depth in your pond so your fish can get away. Raccoons like to perch on the side and stick their hands in to snag the fish.

  • @stevemiller7584
    @stevemiller7584 6 лет назад

    I have watched all of your great videos and you have inspired me to build my own pond. I am building it in about a 13x13 area that is in between my sidewalk and porch. I made the pond 5' in the deepest area. I have run into a few problems that I need some advise with. I built a retaining wall for one area that needed to hold the weight of the waterfall. It is very muddy where I live and just had two of the other sides cave in when I was draining the pond. We backfilled the pond as we filled it in a few areas. My problem now is that I need to either build two more vertical cinder block walls or come up with another solution. I would like to rick the inside but didn't know how much weight the rocks would support. It is hard because I am in a small area with a deep pond. I would love any advise! Is there any way I could send a few pics?

  • @RaiUriarte
    @RaiUriarte 8 лет назад +5

    Hello eric, one question,. How do you calculate how many rocks you need to buy?, I´m in that step right now. 1square meter for the same size you have in this pond will be too much or it is ok?. Thanks again.

    • @ThePondDigger
      @ThePondDigger  8 лет назад +4

      Hey Rai, that's a great question. Here is a how you can really get down to the figure. Measure the length and depth of each shelf. A ton of 10" to 12" rocks will go approximately 20 linear feet. With this math measured against your shelves should be able to put you on the right track.
      If I have a pond that is 16 foot diameter, I will measure the circle and then determine how many 2 foot rocks I will need to complete the installation of the coping stones. Keep in mind I will mix in a couple 3', 1 foot and a foot and a half rocks to break up the look.
      Keep in mind the density of the rock we install could be very different than what material you have available to you so you will have to weigh and measure a ten foot section of stone to determine your numbers for the calculations.
      I typically will want to error on the side of having too much rock rather then not enough. When we finish with the project and we have some extra stone left over we will work the material into the landscape around the water feature.
      I hope that answers your question. It's a little work to figure it out but it's worth it.
      Be sure to send me a video link of your pond when complete. Let me know if you need anything else.

    • @RaiUriarte
      @RaiUriarte 8 лет назад +2

      Many Thanks Eric, I´m building a 3x2 meters pond with 80 cm of deep. I all ready buy the rock so I buy 1square meter of big rock, and half of a square in little gravo, that is mixed with a little medium. When I look at all the stones, all together, it looks like there is too much big rock and I will need more medium size. I also buy a gorgeous flat stone with nice orange and gray colors in it.
      I will made a complete video about it, but now I´m in pause by the liner, the client has a old liner we buy 3 years ago for this project, but, they used for another thing and when I check it I count at least 10 holes in it. So I´m not sure if I should buy another one or repair this one. In Chile is very difficult to buy liner. Actually we don´t have the one you use.

Kids started using city pool so much, I decided to make our pool my experiment...

    • @stevenhabener
      @stevenhabener 10 лет назад

      Sandstone slowly breaks down over time. Without proper routine maintenance, sand will build up in the filter mats and floss/lava stone bags. This will reduce filtration of debris and organic material. Resulting in poor water clarity and living conditions for life. Some sandstone is ok , but not too much.

    I am 13 and and want to build a pond. I don't want to spend the bulk of my money on rocks, where is a good store that I can buy cheap rocks from like Lows or Home Depot

    Is it a bad idea to build a pond, and not put fish in it? I live in Minnesota, so I feel like it would be too much work to try and keep the fish alive. I know you can take steps to make sure the pond doesn't freeze, but I would rather avoid that. THANKS!

      +Jaime Rossiter You can use small minnows in the pond. I think the extra effort to keep fish is worth the it.
