Believe it or not I built it on my own! RM2K and later spent another RM1K for water proof and other filter stuff and pump.

For a good koi pond you should have one far end for water return and the other far end with bottom drains going into the filter and pump chamber. This will give you a straight flow like a river that flow one direction.

If you use the old way where the bottom drains (BDs) are located at the middles of the bottom pond you would have a circular flow that confused the fish. The old way also need you to have one third volume of chamber vs the pond volume where the filter chamber took too much space.

Newer method is to have a lot of aeration and some external filtration system that you need not have to have large filter area for filter chamber.

If you hire someone to built it could cost RM20 to RM40K depends on size and stones that you need to decorate the pond. I just did little decoration. Sometimes simple look nice depend on individuals.

No lori. I used my car. Putting the soil on bags, load into my car drove for some distance and throw and bring back the bags.
