Have you got plenty of surface cover, lilies and the like? I read a pond needs at least 1/2 the surface area shaded otherwise the algae get too much light and take over. I know that barley straw, a bundle thrown in, works wonders for green water supposedly. Not sure where it would be stocked near you?

We have a big natural pool with koi, goldfish and orfe, no filter but we lucky it has a stream running into it (and out the other end) so don't need a pump. It doesn't go green exactly but the blanket weed starts growing this time of year but once the pond weed starts oxygenating and surface plants start growing it sort of balances itself out. We tried getting the blanket weed out one year, 8 barrow loads of it lol, but it just grew back, I think we stirred up the debris in the bottom and gave the algae more to feed on. So now we leave it alone.

Plant some weeping willow or large bush near the pond, try filter out the sun with as much cover as possible.

pond water treatmeat

what you have is suspended green algae is present in all natural aquatic environment and in small quantities it is beneficial.however, when excess nutrients and light are available the algae in your pond can become think and out of control, it can also harm your fish as it can clog your filter and foul the water and irritate the fish's gill and deplete the oxygen in the water mostly at night, you should go to your pet shop and get some green water control

It is quite big, its about 30ft x 14ft at a guess? its only 2-3ft deep though, no liner we just dug a hole and let the stream filll it up. We've got 6 lilys I think, Lidl had some last year quite reasonably priced and they were fine. Its got some fish but I love the wildlife more; whirligig beetles, water boatmen, damselflies larvae and mayflies, saw my first mayfly hatch last night. http://i115.photobucket.com/albums/n...denandpond.jpg

Be careful of leaves falling in from weeping willows etc if you do plant trees nearby for shade. The leaves will rot and cause problems if your pond ices over.

Hope you get it sorted out

Thanks for the offer but i'm down near Cork. The goldfish bred a while back and we have about 100 babies possibly, I've lost count. They are 1-2 inches long, most changed colour. I'll be giving them away if they all reach adulthood. There are 5 or 6 decent sized koi in it and 2 large golden orfe. Don't think they have bred though just the goldfish.
