Imagine diving into a stunning, crystal-clear natural swimming pond, only to spot swirling green wisps below.
It’s a common concern for many pond owners: algae and blanket weed.
Are these aquatic invaders dangerous, and what should you do if they appear? Let’s explore the facts, myths, and solutions, so your wild swimming haven remains a source of joy—not stress.
What Exactly Are Algae and Blanketweed?
Algae and blanket weed are two types of plant-like organisms often found in water. While both are natural, they behave differently:
| Type | Description | Common Issues |
|---|---|---|
| Algae | Microscopic organisms that thrive in water, causing green or cloudy water. | Can impact water clarity and encourage other aquatic nuisances. |
| Blanket Weed | Stringy, fibrous growths that spread across pond surfaces or cling to structures. | Creates tangled mats, choking pumps and filters while being unsightly. |
In small amounts, algae and blanket weed are part of the ecosystem. But left unchecked, they can disrupt the balance and spoil the experience of swimming in your dream pond.
Types of Algae
- Planktonic Algae
- Microscopic algae that float freely in water, often causing green, cloudy water.
- Common in nutrient-rich ponds with lots of sunlight.
- Can create a “pea soup” effect, reducing visibility.
- Filamentous Algae
- Hair-like strands that form mats on the water’s surface or cling to pond walls.
- Sometimes mistaken for blanket weed but generally more dispersed.
- Blue-Green Algae (Cyanobacteria)
- Technically bacteria, not algae, but often grouped due to appearance.
- Forms slimy blooms, often blue-green, red, or brown.
- Can release toxins harmful to humans and animals.
- Diatoms
- Single-celled algae with silica walls, usually golden-brown in colour.
- Thrive in cooler conditions and form slimy layers on submerged surfaces.
Types of Blanketweed
Blanket weed is a type of filamentous algae that grows in fibrous, string-like patterns. It is often grouped into two main forms:
- Floating Blanketweed
- Grows in loose, tangled masses on the water’s surface.
- Easily spotted and removed but can quickly cover large areas if untreated.
- Attached Blanketweed
- Clings to surfaces such as pond walls, rocks, or equipment.
- Harder to remove as it anchors firmly in place.
How Safe Is It to Swim in Algae-Infested Water?
If you’ve ever wondered, “Is swimming in a pond with algae safe?”, the answer depends on the type and extent of growth.
Minor Algae Presence: Generally harmless, especially in ponds with effective filtration systems like ours at Ponds by Michael Wheat.
Toxic Algae Blooms: Rare in well-maintained swimming ponds but can cause skin irritation or worse if ingested.
Blanketweed: Not toxic, but swimming through dense mats is unpleasant and can obstruct movement.
Effective pond management prevents harmful algae and ensures your natural swimming pool remains safe for all.
Why Do Algae and Blanketweed Appear in Swimming Ponds?
Several factors contribute to algae and blanket weed growth. Understanding them helps in preventing these issues:
Excess Nutrients: Leaves, debris, or fish waste release phosphates, which feed algae.
Sunlight Exposure: Warm, sunny conditions boost algae growth.
Inadequate Filtration: Poor systems leave water stagnant, inviting problems.
Traditional ponds relying solely on plants for filtration are more vulnerable. Our unique natural swimming pond design avoids this by combining mechanical, biological, and UV filtration. This approach reduces maintenance and prevents “long periods in new pond syndrome,” a common issue in plant-dependent systems.

Swimming Pond Upgrades start from £30,000 for more information call us today
One client came to us with a pond overtaken by green water and tangled weeds. Having invested £250,000 in a beautiful traditionally made swimming pond they experienced a full year of new pond syndrome and then came a continuous battle with overgrown blanket-weed reducing their enjoyment of swimming in their dream swimming pond without frustration.
The client reached out to us to help, We introduced our award-winning filtration system, Within months, their pond transformed into a haven of clear water. Today, they swim confidently, knowing every dip is safe.
How Can You Prevent Algae and Blanketweed?
Here are four strategies to keep your pond pristine:
Invest in Advanced Filtration: High-tech solutions, like UV sterilisation, kill algae spores.
Skim Debris Regularly: Leaves and organic matter fuel algae. Removing them early saves hassle later. Likewise if you have small pockets of blanket weed scoop it out daily (It makes good fertilizer so I hear!)
Introduce Beneficial Bacteria: These friendly microbes out-compete algae for nutrients.
Control Sunlight Exposure: Plant trees or install shading to reduce direct sunlight. This is why it’s important to consult with a specialist as this will be factored in as part of the design process.
Increase water oxygen levels: Water movement from pumps will help and prevent growth of algae.
Using a system like the Michael Wheat System eliminates the reliance on vast planting zones, saving space while keeping the water clear and healthy.
Comparing Traditional vs. Advanced Filtration Systems
| Feature | Traditional Plant-Based Systems | Ponds by Michael Wheat’s Filtration |
|---|---|---|
| Reliance on Plants | Heavy reliance for filtration | Minimal plant dependence |
| Maintenance Requirements | Labour-intensive and time-consuming Ongoing monthly maintenance is required with the contractor | Efficient and low-maintenance. Maintenance with contractor available however not necessary |
| Filtration Efficiency | Prone to algae blooms | Crystal-clear water consistently |
| Time to Complete Installation | Longer due to plant establishment | Quicker project timelines |
| New Pond Syndrome | 6-12 Months | 1-2 Months |
| Running Costs | Minimal some pumps | The filtration system requires full mains access |
| Longevity | The gravel bed which is part of the filtration system will need a full renovation due to build up of silt | No barriers, built for a long lasting life |
What Should You Do If Algae or Blanket Weed Appears?
If you spot algae or blanket weed, act quickly:
- Remove visible blanket weed with a rake or net.
- Check your pond’s filtration system for blockages.
- Add UV sterilisation or algae treatments compatible with your system.
- Consult expert swimming pond contractors to upgrade your filtration.
Question for you: When was the last time you considered the health of your pond water?
Frequently Asked Questions
1. Are algae dangerous in swimming ponds?
Most types are harmless but can irritate skin if left un-managed. Blue-green algae (Cyanobacteria) is the one harmful algae to humans and animals as it releases to humans and animals. Algae and Blanketweed can become a safety problem when there’s excess and they then become breeding grounds for other harmful micro-organisms.
2. Does your filtration system prevent algae completely?
While algae can appear, our system ensures it never overtakes the pond.
3. Is blanket weed harder to control than algae?
Blanket weed spreads faster, but our UV and biological filters address it effectively.
4. How much does a swimming pond cost?
Prices depend on size and features. Our Swimming ponds start from £75,000 for a Hybrid swimming pond and from £95,000 for a walled swimming pond
5. Can algae damage the pond itself?
If untreated, algae can clog systems and require more costly maintenance later.
