Filters
At Bradshaws Direct we know how important it is to keep your pond clean and your fish healthy. That’s why our range of pond filters are designed to do just that!
Whether you are looking for a basic pond filter, a traditional box filter or a pressurised filter we have just what you need.
A basic pond filter will keep your pond healthy for fish but will not get rid of green water.
Box Filters are like the basic pond filter but with the added advantage of a built in UVC. Some of these can be partially buried but the outlet should always be above the pond water level, usually positioned at the top of a waterfall or by the pond edge.
Pressurised Filters can be positioned anywhere around your garden, even below the water level of your pond. This is particularly useful if you have a raised pond or want to hide the filter away from the pond. The Oase Filtoclear Pressurised Filter (UVC) is a great example.
As well as our selection of standard pond filters, we stock a range of specialist pond filters including koi filters for Koi ponds or well stocked goldfish ponds.

How do pond filters work?
Pond filters operate by removing debris and harmful substances from the water, ensuring a clean and healthy environment for fish and plants. Water is drawn into the filter, where it passes through various media, such as sponges or beads, which trap dirt and particles. In addition, beneficial bacteria break down organic waste, converting ammonia and nitrites into less harmful nitrates. Some filters also feature ultraviolet (UV) light, which helps eliminate algae and pathogens.
How often should pond filters be cleaned?
Regular cleaning is essential for maintaining efficient pond filters, and it is recommended to clean them every 4 to 6 weeks during the active growing season. However, the frequency may vary based on fish load and the amount of debris in the pond. High fish populations or significant debris may necessitate more frequent cleanings. Inspecting the filter monthly can help gauge its needs, ensuring optimal performance.
Do pond filters need to run continuously?
Yes, pond filters should ideally run continuously to maintain optimal water quality. Continuous operation allows for ongoing filtration, which helps to remove debris and harmful chemicals effectively. Additionally, the constant flow supports beneficial bacteria, crucial for breaking down waste. However, it is essential to monitor the filter’s performance, as periods of lower activity, such as during winter, may allow for temporary shutdowns without harming the ecosystem. If you decide to turn off the filter, ensure you know when to do so to avoid adverse effects.
Do fish get caught in pond filters?
Generally, fish should not get caught in pond filters if they are suitably designed and sized for the species present. Most modern filters come with protective screens or similar measures to prevent fish from entering. However, small or young fish are more at risk and should be monitored closely. Providing adequate hiding spots in your pond can also reduce the risk, giving fish safe spaces to retreat and helping them avoid filter intake areas.
