If you keep a garden pond anywhere in Northern Ireland, you’ll know the frustration of blanketweed. Those long, stringy green strands seem to appear overnight in June and July, wrapping around plants, clogging pumps and turning a beautiful pond into a tangled mess. The good news? It’s one of the easiest pond problems to fix when you use the right product.
Why Blanketweed Loves Northern Ireland Ponds
Our long summer daylight hours combined with nutrient-rich tap water create the perfect growing conditions for blanketweed (string algae). Rainfall washing fertiliser and organic debris into ponds across Antrim, Down and beyond only adds fuel to the fire. Once established, blanketweed can double in size in a matter of days.
The Solution: Cloverleaf Blanket Answer
At Clearly Aquatics, the number one blanketweed treatment we recommend to pond keepers across Northern Ireland is Cloverleaf Blanket Answer 2kg. It’s a blend of natural minerals and enzymes that breaks down blanketweed without harming fish, filter bacteria or pond plants.
The 2kg tub treats up to 20,000 litres, making it ideal for medium to large garden ponds and koi ponds alike. Most customers see the weed loosening and breaking apart within days of the first dose.
How to Use It
- Remove as much loose blanketweed by hand as you can first
- Mix the measured dose with pond water in a bucket
- Pour evenly around the pond, ideally in the morning
- Keep your air pump running, as the treatment works best in well-oxygenated water
