Dealing with blanketweed in ponds

Blog post written by Gary | 27 April 2016 | Category: Pond maintenance

At this time of year as the sun becomes stronger and the weather becomes warmer, blanketweed in ponds can grow very quickly covering the pump and causing it to fail due to the impeller becoming clogged. Also the blanketweed becomes entangled in the marginal and oxygenating plants making the pond look unsightly.

There have been many treatments brought out to clear blanketweed from ponds, however most will struggle to keep the blanketweed under control. Having tried various treatments we have found the most effective to be a product called Blanket Answer. We have been selling this product for the last five years and on only two occasions have we had a customer say it did not keep the blanketweed under control.

Blanket Answer is a unique blend of minerals and enzymes and is safe for all fish, wildlife and biological filter systems. Once Blanket Answer is added to the pond, the water will initially go milky cloudy which will clear in a few days. The blanketweed will then die back. A further treatment may be added if there is a sign the blanketweed is starting to reappear.

To get the best from Blanket Answer, have a pump running continuously to help disperse the treatment throughout the pond. Also as with any treatment having good oxygen level saturation helps fish like sturgeon and orfe.

We have four sizes of Blanket Answer:

200g for ponds up to 2,500 litres: £9.59
800g for ponds up to 10,000 litres: £22.99
2000g for ponds up to 25,000 litres: £44.79
4000g for ponds up to 50,000 litres: £75.99
