Blanket Weed (Spirogyra) Treatment & Maintenance

(90 days money back + 2 Years extended guarantee)

For pond owners with larger water features or severe algae problems, blanket weed can become a constant battle. This green filamentous algae (Spirogyra) grows in spiral filaments that quickly tangle together into dense mats. Left untreated, blanket weed clogs pumps and filters, blocks pipework, restricts sunlight, and reduces oxygen levels, threatening the health of fish and aquatic plants.

The EL-WW-ECO+ blanket weed controller is designed to tackle these challenges in ponds up to 18,000 litres (around 4,000 gallons). Building on the proven ECO model, the ECO+ uses a powerful dual-antenna system and advanced two-stage action to provide stronger and more reliable blanket weed control.

Unlike chemical pond weed treatments or manual clearing, the ECO+ offers a permanent, maintenance-free solution. By generating a controlled, low-frequency magnetic field, the unit changes the balance of calcium forms in the water. This disrupts the growth mechanism of blanket weed, forcing rapid but unsustainable growth that the algae cannot maintain. The result is a long-term blanket weed cure that works continuously, without altering water chemistry or affecting fish, plants, or beneficial pond life.

Before

After

Because it targets Spirogyra’s unique cell structure, the ECO+ is highly effective against blanket weed while leaving the rest of your pond’s ecosystem safe. Over time, you’ll notice clearer water, fewer algae blooms, and less maintenance. Pumps and filters remain free from blockages, saving you the effort of dismantling and cleaning equipment.

Designed with convenience in mind, the ECO+ is simple to install, completely chemical-free, and runs automatically once fitted. The unit consumes only 3 watts of power – about the same as a digital alarm clock – making it cost-effective to operate. Built-in self-monitoring ensures reliable operation, with LED indicators to show the system’s status and provide peace of mind.

For ponds up to 9,000 litres, the standard EL-WW-ECO model is recommended. For larger ponds, or where blanket weed is especially stubborn, the ECO+ delivers the additional performance needed for long-term pond weed control.

Simple installation:

Fitting the ECO+ Blanket Pond Weed Controller is quick and requires no plumbing or specialist tools:

  1. Place the two antennas around the pond’s pipework, ideally between the pump and filter.

  2. Mount the control unit close to the pipe using the screws provided.

  3. Plug the power supply into a standard UK socket.

Once installed, the ECO+ runs automatically and continuously, keeping blanket weed under control without the need for further intervention.
