A clean pond isn’t just about appearances; it’s essential for the health of your fish and the balance of your pond’s ecosystem. At Koi Water Garden, we provide expert pond cleaning services designed to tackle algae, blanketweed, sludge, and water quality issues, restoring your pond to its best condition.
With over 30 years’ experience in koi and pond care, our team can handle everything from routine cleaning to full pond overhauls. Whether you want us to take care of everything or you’d like some expert advice to do it yourself, we’re here to help.
As water begins to warm up in spring, algae begins to bloom and can take over quickly. One of the most common problems is blanketweed, a string-like algae that clogs pumps and filters if left untreated. It can also trap and harm fish if it becomes too dense.
Other ponds turn into what many call “pea soup”, where green water clouds the pond due to microscopic algae. This will only worsen unless your UV filtration is working correctly with a fresh bulb (we recommend replacing bulbs every 6 months).
Left untreated, algae and sludge build-up can damage equipment, reduce oxygen levels, and put your fish at risk.

If you prefer to carry out some of the cleaning yourself, here are a few essential tips:
Even with the best DIY care, some ponds benefit from a professional deep clean once or twice a year, especially heavily stocked koi ponds or systems that struggle with persistent blanketweed.
If your pond is looking tired, clogged, or overrun with blanketweed, our team can restore it quickly and professionally.
With Koi Water Garden, your pond will be cleaner, healthier, and a stunning focal point in your garden.
