Greetings - i had posted on garden banter but saw a message saying
everyone was now on here, i'm afraid i've not used google groups
before so hope i'm doing everything ok.

Anyway i have bought a house with a pond, not a big pond. It has a
fish mate 2000 fountain and just discovered the pump round the back (a
fish mate 2500UV) which feeds a mini waterfall.

I've just emptied out the pond as it was filthy, full of leaves and
muck and thought i better find out what this equipment actually does.
Now as i say i'm a complete novice with ponds so please be patient!

What does the pump do (apart from feeding a flow of water to the mini
waterfall) does it clean the water? is it just for keeping fish. We've
not had the pump on since moving in would this have stopped the pond
becoming so mucky.
I don't know if i should open up the pump and replace or clean
anything before i fill the pond for summer.

Appreciate any guidance on this!
phil
