Re: Here's mine I had the pond upgraded this time last year, so the decking, pergola and screen were pretty new when I took the photo a week or so after it was finished.
The spec is approx 14'x10'x3', 4" bottom drain in centre straight into a Cloverleaf (biggest one) brushes/jap matt/ foams/agragog into a maga sand filter via swim pool pump, through a Cloverleaf 55watt stainless steel U.V and than back through 2 venturis.
Up until Mid May the water was crystal, you could see dust on the bottom, then along came the dreaded blanket weed. I've treated it with Evolution Aqua b/weed killer. It's certainly cleared it, but has made the pond go very cloudy. I've currently got a sheet of filter wool in, to try and capture it as it was going straight through the system.
More improvements are in the pipeline, I'm going a foot-18" deeper and having it concreted and either G4'd or fibre glassed as the 10 year old liner has sprung a leak. So watch this space.
