Filter sludge #1
I have had a small (8 ft diameter) pond running for about 9 or 10 years with a green geenie for filtration and everything was ok until I did an upgrade with a new uv filter as the one fitted in the filter could not keep up with the green algae, I forgot to turn the uv filter on over the winter and a carpet of algae formed over everything.

At the beginning of the year I turned it back on and now I find that the filter gets clogged really quickly with a magnolia coloured sludge after about two weeks.

What's gone wrong I wonder.
