    I was asked in a private message about the holding tank. It is being filtered with the pre-existing bead filter. I am not sure how the fish are taking the stress of vibrations etc., especially since the heavy equipment was moving within a couple of feet of the tank, but the water tests ammonia-free. To prevent jumping, the tank is tightly covered, with the in-flow going through the cover rather than under it.

      What a big project Mike, congratulation.
      I wish you a good weather all next month so the works can go easier and faster

        HI Mike the other pond was beautiful, may I ask why you wanted to change the pond? It looked to be a very big pond. How big is this pond? I am glad you decided to share the work with us as I have not had a look at your pond before and now I know what it looked like before you tore it up and will know what the new one will look like. Must be nice to have plenty of money to do a project like this, it hurts just thinking about it, it cost more than my mud ponds being built.

        I got to meet Carl at the Atlant Koi Show last September and I really liked him, that man works hard. He was bowling his koi to sell to customers after his long trip and done it like he had rested all night. I dont know how he had the energy to even get up out of a chair. Nice guy. When I notice that Keirin Koi was there I was so happy, I got me a koi for him and placed him in the show.

        I would like to see your koi, if you have room how about takeing some shots of them. You dont live that far from me and one day I might just be in your area and I could stop by and see the pond and koi in person. Now I would really love that. How about it?

          Mike, you lucky guy. I was at Keirin Ponds last December for the opening of his 20,000 gallon indoor pond. At that time I went to a demonstration of the spray on liner; it looks like the best pond liner of all to me.

            Hey Mike what is the cost of this project? I mean if you dont mind me asking. I have a guy here in San Jose that is pretty much doin the same thing as Carl...and told me that 15mins after spraying the pond with the stuff you can fill it with water.....
            The world sleeps as the chance to learn something new passes.

              KFG: The old pond a little over 4500 gallons. Definitely low-tech, labor intensive to maintain, only 4' deep at the deepest spot and poorly configured/shaped. Due to site limitations, personal foibles (garden issues & aesthetics), and zoning requirements, the new pond will not be my "ideal" pond. But, even I draw the line at razing the house to make the pond fit better.

              Tony: Since I am doing virtually nothing myself, the cost is in the same range as using gunite. In many ways gunite allows more flexibility. In my situation, however, the extra time involved and the lack of contractors truly knowledgeable of koi pond design makes this approach work much better ... if it works!

                And, here's some progress shots in late afternoon, when it had cooled down to about 91F in the shade ... and these guys have been in the sun most of the day. It was a scorcher, with not a cloud in the sky all day.

                  And here they are still at it as the sun disappears. (It is cooler when it gets dark!)

                    Progress shots in the morning when the light is better.

                    Oh, in case you have the idea that the whole yard is getting destroyed, everything out of the line of fire is doing fine.

                      fascinating to behold! With all your experience i might have you drop by and give me a bid to redo mine! (lol) thanks Mike, for sharing!

                        Mike M.

                        Great Pics, great project...A few questions that I'm sure you've done the research on, and have the answers to:

                        1. Your soil looks sandy is this why you didn't spray the polyurea directly onto the sides of the pond hole?

                        2. Since you seem to be using hollow tile for sides of pond are you going to pour a concrete bottom.

                        3. If you have a concrete bottom and block walls, why didn't you render the tile and seal the pond with CIM.

                        The answers to these questions will be great for future reference on new ponds...

                        One last request...While the pictures are great, they don't really show the relationship between foot prints of the "Old" and "New" ponds... Will you post a "Top View" sketch of your property showing house and ponds... Just how big will be new pond be???

                        Now that you're completing your pond, all you have to do, is save 25 grand to buy a momotaro Jumbo Tosai to swim in it...

                        Good luck with the completion of the pond...Am looking forward to the finished product...

                        Aloha! Mike

                          MikeT: I'll get to your questions, but a bit rushed this morning. The concrete block has rebar running through the open space ... a hint of what is to come.

                          Status shots just after sunrise: The filter pit getting mortared block walls. The pond with un-mortared block walls rising. And, from the bottom looking across.

                            The pond is kinda egg shaped. The widest interior width is 15.5'. The longest dimension is 22.5'. A tad smaller than I'd like in a perfect world, but I was not willing to sacrifice camellias. [The hole was another 1.5' (approx) all around to accomodate block and overdig.] Side walls 5'. Depth at bottom drains is over 6' ... a bit deeper than originally planned. Due to shifting the pond a bit due to site conditions, I was not sure just what the size would turn out to be. I took interior dimensions this morning.

                            More later. It will be a busy day. Rain expected tomorrow.

                              This is an intersting project MikeM thanks. I to prolly in a few years may want to Expand. Don't have to but am interested in this application. I think I like it only because with gunite looks like it takes so much water volumne away from original design and the repair factor looks much easier.

                              Cannot wait for more pics Mike and thanks

                              It's a living creature (chit happens)

                                Looks great so far and will all come together quite nicely I am sure when finished. A question regarding the construction methods if you will...I noticed that you used standard 8 X 8 X 16 blocks for the qt/hospital tank. Did you consider using double open ended blocks? They would have allowed the grout to flow around and between all of the blocks creating a more solid fill than the columns of the standard blocks. You could have used all bond beam blocks also in that. You also indicated that you were not going to motar the the blocks for the pond. Are you going to grout them?

                                I am enjoying the pictures and look forward to more.
