There are many benefits from having a blanket weed controller fitted in your garden pond.
It can inhibit the growth of Spyrogyra, cleanse the water, and help keep your pond healthy.
 This can be a massive problem if not treated early and can literally choke the pump and filter of air, and make the pond water look extremely dirty and unpleasant.
So what is a blanket weed controller? It does exactly what it says on the tin.
It controls the growth of Spyrogyra within your pond, and can be easily installed by even the most novice diyers.
It is usually attached between the pump and the filter, but can be fitted anywhere around the circulating loop.
