Pond BUILD day 3 Filtration

What happens here

This video provides an overview of installing a large-scale backyard pond, with a particular focus on the setup of an advanced biological filtration system. It details the process of excavating the pond basin, layering underlayment and liner, precisely placing large boulders using heavy machinery, and constructing a specialized under-gravel filter system designed for optimal water quality. The project demonstrates techniques for stable rock placement and the scientific principles behind efficient biological filtration in a pond environment.
