Hi I'm building a new pond soon and would like your opinion the size is 36'x14' with 3 - 4" bottom drains. 7' deep and made of 8"cement blocks filled with concrete and reinforced with re bar. I'm posting a drawing I did of the new Koi pond and any improvements you can think of would be greatly appreciated. Also some pictures of the location, and of our old pond and our mutts. My last pond as I understand now was a water-garden this one will have no plants or mung hiding rocks
Some questions I have are, and there will be more.
1] Should the block on the dirt side be sealed & waterproofed?
2] The distance of pipe from bottom drains, is there a rule the shorter the better because were I would like to put the filtration is far away and the least amount of bends as possible?
3] Is it better to have the drains angle up to the filter or run them on a smaller slope like 5 degrees then straight up?
