How to make a fish pond with cement?

1. Determine the size and shape of your pond.
2. Clear the area where the pond will be located and level it by removing dirt, rocks, and other debris.
3. Dig a hole that is deeper than the finished pond height, making sure that the sides are smooth and even.
4. Line the hole with a heavy-duty plastic film to prevent leaks.
5. Place a layer of gravel at the bottom of the hole and tamp it down firmly.
6. Add an underlayment of blanket fabric over the gravel and around the sides of the hole.
7. Mix cement according to the manufacturer’s instructions, and pour it into the hole.
8. Shape the concrete walls of the pond with a trowel as it hardens.
9. Let the cement cure for the recommended time period.
10. Install filters, pumps, and other equipment needed for your pond.
