Frequently Asked Questions — Pond Supplies

What pond supplies do I need to build a backyard pond?

A basic backyard pond requires a pond liner (or preformed shell), a pond pump, a filtration system (pressure filter or bio-filter), and water treatment to establish healthy water chemistry. For fish, you'll also need a UV clarifier to control algae and keep the water clear. Browse our Pond Kits for everything bundled together.

How do I choose the right pond filter?

The right filter depends on your pond volume, fish load, and whether you have direct sunlight. As a rule, choose a filter rated for at least 1.5× your pond's water volume. Our team can help — call 1300 238 288 or read our guide on Selecting Your Pond Filtration System.
