One year on and still a brown, murky pond

Hi,

I excavated a 5 x 3m pond last April, lined it and filled it, bought
masses of oxygenating plants and potted up some pond plants but now one
year on, despite clearing all debris in the autumn and again this week,
the water is brown, stagnant and all but a handful of oxygenators are
dead.

I want a natural wildlife pond without a pump if possible. I live in
the Highlands of Scotland, about 1000m above sea level and the soil
around is naturally acidic. Our tap water is pure, with no additives and
the pond was filled by hose. I'm at the point of thinking about filling
the flaming thing in again.

Can someone help please?
