Hello all,

Can anyone help?

When is the best time to clean my small pond (I live in the UK and it's
winter here)? It is around 250 gallons and contains around 15 goldfish
but the water is very murky and contains plenty of leaves from the
recent autumn. I'm also aiming to install a UV combi filter at the same
time.

I know the fish have bred in the past so I don't want to upset their
mating season so do I do it now before they get too frisky or wait
until summer/autumn?

Many thanks,

John.
