The Pond One ClariTec 3000 Pressurised Filter is a compact and easy-to-install pond filtration system with a built-in 9W Ultra Violet Clarifier (UVC), designed to help keep pond water clear, clean and healthy.

With a 15.5 litre filter capacity, mechanical and biological filtration and integrated UVC technology, the ClariTec 3000 is an excellent choice for small ponds and water gardens up to 3000 litres, depending on fish stocking levels and the amount of sunlight your pond receives.

The pressurised design makes this filter particularly useful when you want to create a neat and discreet pond filtration system, as the unit can be partially buried to help it blend into the garden.

What Size Pond Is the ClariTec 3000 Suitable For?

The recommended pond capacity depends on fish stocking levels and sunlight exposure:

• Low fish stock & limited sun exposure: up to 3000L

• Average fish stock & average sun exposure: up to 1500L

• High fish stock or extended sun exposure: up to 750L

If your pond has a high fish load or receives a lot of direct sunlight, choosing a larger filtration system may be appropriate.

Built-In 9W UVC for Clearer Pond Water

The ClariTec 3000 features a 9W Ultra Violet Clarifier (UVC) designed to help control suspended algae and improve water clarity.

As pond water passes through the UVC chamber, exposure to ultraviolet light helps reduce the microscopic organisms responsible for green water, helping you maintain clearer-looking pond water.

The UVC ballast is positioned remotely and comes with a 10 metre cable, providing flexibility when installing the filter.

Mechanical & Biological Pond Filtration

The ClariTec 3000 combines mechanical and biological filtration to help maintain healthier pond water.

The filter media captures debris and particles from the water while providing surface area for beneficial bacteria. These bacteria form an important part of biological filtration by helping process waste within the pond.

The filter comes supplied with its filter media, so it's ready to install.

Compact Pressurised Pond Filter

The pressurised design allows the ClariTec 3000 to be installed neatly into your garden and can be buried for a more discreet appearance.

Because the filter is pressurised, it can also be used as part of a pond system where filtered water needs to be returned to the pond via a hose or water feature.

Its compact design makes it a practical choice for smaller ponds where space around the pond is limited.

Easy Pond Filter Maintenance

The ClariTec 3000 features a bypass function, allowing you to clean the filter without needing to dismantle the entire system.

This makes routine maintenance simpler and helps you keep your pond filtration system operating effectively.

Regular maintenance is important for maintaining good water flow and filtration performance.

Complete Pond Filter Kit

The ClariTec 3000 is supplied with filter media and hose connectors, making installation straightforward.

The filter accommodates hose fittings from 19mm to 37mm (3/4" to 1.5"), giving you flexibility when connecting it to your pond pump and existing pond plumbing.

Choosing the Right Pump for Your Pond Filter

Your pond pump needs to be selected carefully to ensure the filtration system receives an appropriate flow rate.

When calculating the pump you need, remember that the actual flow at the filter will be affected by hose length, hose diameter and bends in the plumbing.

As a general guide:

• Every 1 metre of hose adds approximately 10cm of head height

• Reducing the hose diameter by one size can add approximately 1 metre of head height

• A 90° bend can add approximately 1 metre of head height

• A 45° bend can add approximately 50cm of head height

For this reason, don't choose a pond pump based solely on its maximum litres-per-hour rating. The pump's flow at the required head height is what matters when setting up your pond filtration system.

If you're unsure which pond pump and filter combination is right for your pond, contact our team at We Know Water Gardens for advice. We can help you choose the right filtration system and pump for your pond based on its size, fish load and setup.
