Its our old pond but this year has a new problem, for the first time
in over 30 years we are getting large quantities of blanket weed, not
added anything to the pond in years nor applied any fertilizer to the
bed behind so I am at a bit of a loss as to why, but perhaps more
importantly what to do to get rid of it or at least reduce the amount.

At the moment I am pulling out large quantities every other day, do I
just keep going and hope I eventually reduce the nutrient levels or is
there a quicker and easier method

You can see a picture of the pond here

You need to starve the blanket weed from it's food source - algae.

If you can bury some electric cable to run a small pump with a UV lamp
inside.

Blagdon is a name you're familiar with :-

Bottom of (above) page gives the various litreages. I wouldn't bother
with the spray outlets :-)


I will look into the UV filter idea, I need a good bit more than the
6000 lt pump illustrated though as the pond is 14,000 lts!
