Everything You Need to Know to Build the Perfect Backyard Pond

A clean, healthy pond requires a few key elements to keep water contained, fresh, and filtered.

Water agitator
Keeps water oxygenated. Fountains, waterfalls, and bubblers are all agitators.

Filter
Cleans the water coming from the pump.

Liner
Prevents water from leaking into the ground.

Underlayment
Protects the liner from punctures and stretching during installation.

Pump
Circulates water through the filter and up to the waterfall or fountain.

Covered GFCI outlet
Feeds power to the pump. Trips automatically to prevent lethal shocks.
