Pond Maintenance
Pond maintenance is about keeping on top of the jobs that make your pond easier to enjoy: clearing debris, looking after plants and checking that the pump and filter are working as they should. We maintain garden ponds, koi ponds, wildlife ponds and ornamental ponds across Kent, London and the South East.
We keep ponds ourselves, so we understand that the right routine has to work for both the pond and its owner. Tell us what you find difficult, what equipment you have and how much care you want to handle yourself. We can then discuss regular visits, seasonal help or a one off visit to deal with a particular problem.
If a pond has been neglected or requires more intensive work, a full pond clean may be recommended before moving onto ongoing maintenance. This service forms part of our wider pond care services across Kent, London and the South East.
Why Regular Pond Maintenance Matters
Even a well designed pond will deteriorate without regular care. Leaves, plant debris, fish waste, uneaten food, and airborne nutrients gradually accumulate, placing increasing pressure on the pond’s filtration system and biological balance.
Without proper maintenance, this can lead to:
• Blanketweed and algae outbreaks
• Poor water clarity and unpleasant odours
• Sludge build up on the pond floor
• Reduced oxygen levels
• Stressed or unhealthy fish
• Premature failure of pumps and filters
Routine maintenance keeps these issues under control and allows problems to be identified early, reducing disruption and long term costs.
Our Pond Maintenance Services
We offer flexible pond maintenance services based on the size, type, and condition of your pond. Maintenance can be arranged as regular visits or as seasonal support, depending on what your pond requires.
Regular Pond Maintenance Visits
Regular maintenance visits are ideal for ponds that need consistent care throughout the year. During these visits we focus on keeping the pond clean, stable, and running efficiently.
Typical tasks include:
• Removing surface debris and organic waste
• Cleaning skimmers and pump intakes
• Checking water level and circulation
• Inspecting pumps, pipework, and fittings
• Observing fish behaviour and overall pond condition
We can also explain which checks and small jobs need attention between visits. The frequency of professional maintenance should fit around the pond and the care you already provide, rather than replace every day to day check.
Spring and Autumn Pond Maintenance
Seasonal maintenance is especially important during periods of change.
Spring maintenance helps reset the pond after winter, removing debris, restarting filtration correctly, and preparing fish and plants for increased activity.
Autumn maintenance focuses on leaf removal, plant control, and reducing organic material before winter, helping to minimise sludge build up and water quality problems during colder months.
Filter System Servicing and Maintenance
A well maintained filtration system is critical to pond health. We service and maintain all types of pond filters, including:
• Pressurised canister filters
• Multi chamber filter systems
• Box and gravity filters
• Screenmatic filters
• Drum filters and advanced filtration systems
Filter servicing may include cleaning sponges or screens, flushing waste outlets, inspecting filter media, checking seals, and replacing worn components where required.
Where existing filtration is undersized or outdated, we can advise on upgrades that reduce ongoing maintenance and improve water clarity.
Pond Plant Maintenance and Control
Uncontrolled plant growth can quickly overwhelm a pond, restrict water flow, and contribute to nutrient problems. Correct plant management improves both appearance and water quality.
Our plant maintenance service includes:
• Pruning and thinning aquatic plants
• Splitting and repotting water lilies
• Controlling oxygenating weed growth
• Removing excess marginal plants
• Replanting using high quality aquatic planting materials
Blanketweed and Algae Control
Blanketweed and algae are common pond problems, particularly in nutrient rich systems. We use professional treatments and proven management techniques to control algae safely and effectively.
Rather than simply treating symptoms, we aim to identify the underlying cause and reduce the likelihood of regrowth.
In larger ponds or more complex systems, long term nutrient control may be recommended as part of an ongoing maintenance strategy.
Pond Drain and Clean Service
If significant sludge, overcrowded planting or neglected areas cannot be dealt with through routine care, we can assess whether a full pond clean is appropriate. We do not recommend draining a pond simply because a set number of years has passed. The condition of the pond, its fish and wildlife, and the work actually needed guide that decision.
This service includes:
• Safe removal and temporary housing of fish
• Full draining of the pond
• Removal of sludge and debris from the pond floor
• Deep cleaning of filters and pipework
• Controlled refilling and rebalancing
Drain and clean work is often carried out alongside structural repairs or relining where required.
Honest, Professional Pond Care
We do not offer generic maintenance packages. Every pond is different, and our maintenance service is tailored to suit your pond’s size, filtration system, stocking levels, and overall condition. We focus on doing the job properly rather than rushing through tasks.
Whether you need regular maintenance, seasonal support, or help getting a neglected pond back under control, we’re always happy to offer honest advice.
We look after our own ponds as well as those of our customers. Find out more about Matt, our experience and the team behind That Pond Guy.
Ongoing pond care in Maidstone
Our Maidstone cleaning and maintenance project shows how regular care and occasional larger jobs can work together. In her 2022 review, Hazel describes years of pond maintenance, cleaning and replanting when required, and advice about her pump, filter and UV equipment.

Pond Maintenance Frequently Asked Questions
How often should a pond be maintained?
The right interval depends on fish numbers, feeding, filtration, planting and how much care you provide between visits. A heavily stocked koi pond and a lightly planted wildlife pond need different routines. We can agree suitable visits after assessing your pond, and explain which checks you should continue yourself. Seasonal changes may mean the routine needs adjusting.
What does professional pond maintenance include?
Professional pond maintenance typically includes removing organic debris, cleaning skimmers and pump intakes, checking water circulation, inspecting filtration systems, monitoring fish health, and identifying early signs of problems such as algae growth or equipment failure. Depending on the pond, maintenance may also involve plant management, blanketweed control, filter servicing, and water quality assessment.
What happens if a pond is not maintained properly?
Without regular pond maintenance, organic waste and sludge gradually build up on the pond floor. This leads to poor water quality, unpleasant smells, algae outbreaks, reduced oxygen levels, and increased stress on fish. Over time, neglected ponds often require far more disruptive and expensive work such as full drain and clean services or major filtration upgrades.
Is pond maintenance different for koi ponds?
Yes. Koi ponds require a higher level of maintenance than wildlife or ornamental ponds. Koi produce more waste, are sensitive to water quality changes, and rely heavily on efficient filtration. Koi pond maintenance focuses on keeping ammonia, nitrite, and phosphate levels under control, ensuring filters are functioning correctly, and maintaining stable oxygen levels.
Do I need pond maintenance in winter?
Yes, although winter maintenance is usually lighter. In winter the focus is on keeping water flowing, preventing excessive debris buildup, and ensuring pumps and filters are protected from frost. Autumn maintenance before winter is especially important, as removing leaves and organic material helps reduce sludge formation and water quality issues during colder months.
How often should pond filters be cleaned?
This depends on the type of filter and stocking levels. Some filters require regular light cleaning, while others are largely self cleaning. Drum filters and advanced systems still benefit from inspection and servicing to ensure sensors, spray bars, and waste outlets are working correctly. Over cleaning filters can be just as harmful as not cleaning them at all, as it can disrupt beneficial bacteria.
Can pond maintenance help with blanketweed and algae?
Yes. Regular pond maintenance plays a key role in preventing algae problems. Removing organic waste, managing plants correctly, and maintaining filters reduces nutrient levels that algae feed on. Where algae or blanketweed is already present, professional treatments can be used safely, alongside long term nutrient management, to reduce regrowth.
When does a pond need a drain and clean?
A drain and clean may be appropriate when accumulated sludge, excessive plant growth or neglected areas cannot be managed through routine care. It is not an automatic job every few years. We assess the pond before recommending disruptive work, particularly where established plants and wildlife need protecting. Cleaning can also form part of an agreed repair or relining project.
Is professional pond maintenance safe for fish?
Yes. Professional pond maintenance is carried out with fish safety as a priority. Care is taken to avoid sudden water changes, preserve beneficial bacteria, and minimise stress. Where deeper cleaning or treatments are required, appropriate precautions are taken to protect fish health throughout the process.
Can pond maintenance improve water clarity?
Maintenance can improve clarity by removing suspended debris and helping filtration work properly. Green water, blanketweed and disturbed sediment need different responses, so we first look at the cause. Clear water alone does not confirm that conditions are suitable for fish; water testing and observation are still important.
Do you maintain wildlife ponds as well as koi ponds?
Yes. Wildlife ponds require a different approach to koi ponds. Maintenance is usually lighter and focuses on preserving habitats, controlling excessive plant growth, and maintaining water flow without disturbing wildlife. Any work is planned carefully to avoid harm to frogs, newts, insects, and other pond life.
How do I know what maintenance my pond needs?
Every pond is different. Factors such as pond size, depth, fish stock, filtration type, surrounding environment, and water source all affect maintenance requirements. An initial visit allows us to assess the pond properly and recommend a realistic maintenance plan based on its actual condition.
Can regular pond maintenance save money long term?
Yes. Routine pond maintenance helps prevent major problems such as pump failure, filter damage, fish health issues, and severe sludge buildup. Addressing small issues early is far more cost effective than carrying out major corrective work later.
Do you offer one off maintenance visits?
Yes. One off maintenance visits are available for customers who need help at specific times of year, before selling a property, or when a pond has been neglected. After an initial visit, we can also advise whether ongoing maintenance would be beneficial.
What areas do you cover for pond maintenance?
We maintain ponds across Kent, London and the South East, including Essex. Send your postcode so we can confirm coverage and discuss whether a regular visit or one off maintenance appointment is suitable for your location and pond.
