Are you going to build a new koi fish pond? Maybe you will face lots of choice. How to choose the best advice? Here is one example about how to build koi pond.

“I am planing to have the garden laid out with fall of about 4-5 ft between top and lower koi fish ponds(surface elevation) the top pond(6x6x2maxdepth)to be feed from a short stream feed from a water fall filter unit. The lower pond is feed by stream which will have 4-6 steps.The lower pond will be approx 25x12x5-6 ft The idea is to have the lower koi fish pond about 1ft above a stone patio area. The pond/water garden will be a japanese style setting and I intend to plant clumping bamboo as a screen to the wood fence along the property line. I am erecting a split bamboo fence around my lot but it was Oct before it arrived so the first thing next spring is to erect that then I can start on my pond, I cannot wait.”

You can “paint” the cut roots with the tar stuff used to seal cut branches. Beyond that, people use old carpeting under their liners to protect it from sticks and rocks and other things that might puncture it. Any local carpeting store would probably be happy for you to haul off some old carpet.

If you will want to build up the outside perimeter of your koi fish pond to be at least 6″ above the regular ground level. This is so that when you get a pouring rain, water will not run off your lawn and into the pond. Yard chemicals can be deadly to fish. So before you bulid Koi Fish Pond, you should consider about everything.
