Creating a Brilliant Pond System: Your Guide to Clear, Healthy Water

How to Set Up a Pond System for Clean, Healthy Water

Building a garden pond is a brilliant project, but keeping the water clean and clear should be high on your list of priorities. Green algae, harmful bacteria, and debris can quickly spoil your pond—especially if you plan to keep fish like goldfish or Koi. Luckily, with the right pond system, you can turn your backyard feature into a thriving, crystal-clear haven. In this guide, we’ll walk you through the essentials of setting up a pond system, from filters to pumps and more.


Pond Filters: The Core of a Clean Pond

A pond filter is your first defence against murky water. Much like an aquarium filter, it draws pond water through chambers that trap bacteria, debris, and green algae. Choosing the right pond filter depends on your pond’s size, so calculating its volume is crucial.

To work out your pond’s volume:

  1. Measure the length (at its longest point) and width (at its widest point) in metres.
  2. Multiply these to get the surface area.
  3. Multiply the surface area by the average depth to find the total volume in cubic metres.
  4. Convert to litres (1 cubic metre = 1,000 litres).

For a quick fix, try our to do the maths for you. Once you’ve got your pond’s volume, browse our top-notch to find the perfect fit.

Filter Pumps: Keep Water Flowing and Fresh

A filter pump is vital for circulating water evenly through your pond system. Specially designed for ponds, these pumps handle solid particles and debris, ensuring your filter works at its best. The secret to a healthy pond is picking a pump with the right flow rate—the amount of water it filters per hour.

Here’s a handy guide to flow rates:

  • Plant-only ponds: Aim for a flow rate of half your pond’s volume per hour.
  • Goldfish ponds: Filter at least ¾ of the pond’s volume hourly.
  • Koi ponds: Match the flow rate to your pond’s full volume per hour, as Koi produce a fair bit of waste.

Use your pond volume calculation to compare models. Have a look at our range of to keep your water sparkling clean.


UVC Units: Say Goodbye to Green Algae

Fancy an extra boost for your pond system? Consider a UVC unit. These clever devices use UV bulbs to wipe out green algae, leaving your water pristine. They’re a favourite among fish keepers who want a clear view of their goldfish or Koi. Pair a UVC unit with your filter and pump for a cracking setup.

Individual Units vs. All-in-One Systems: What’s Best for You?

When setting up your pond system, you’ve got choices:

  • Individual units: Buy filters, pumps, and UVC units separately for a bespoke setup tailored to your needs. Ideal for pond enthusiasts who love a hands-on approach.
  • All-in-one systems: These bundle everything into one easy-to-install unit. Perfect for beginners or busy pond owners, they’re submersible, simple to plug in, and keep wiring to a minimum.
