Blanket Weed Treatment

Blanket weed is one of the most prolific problems in pond keeping and one of the hardest to overcome. Fortunately, at Envii we offer a small but effective range of blanket weed treatment.

Our treatments offer a fast solution for killing blanket weed and preventing it from returning. Whether you have blanket weed that floats on the surface of the water or submerged below the surface of the water. We have specific treatments to tackle both varieties, each with a unique method of preventing new growth.

Our blanket weed treatment products are safe to use and pose no danger to any fish, plants, wildlife or pets.
