Dusty substance underwater in pond

lukegregory

Hi all

Can anyone help me to identify and resolve this dirty/dusty appearing substance that's starting to takeover the pond? The water itself is very clear, I have a pump with multiple filters. This just settles on top of substrate, pond bottom and sides, pots etc. Underwater it appears quite wispy/dusty.

Any help very gratefully received.

Many thanks

Fish poo accumulation?

I will be interested in the answers/suggestions for this as we have the same problem. Our pond has been slowly built over the past year (daughter doing all the work herself). Water is beautifully clear but all the stones, rocks, ledges and shallow beach areas are covered with a fine creamy/yellowish dust. Plants have been added and a month or so ago we purchased a filter/pump/fountain thingy. Two days ago we added 7 small fish and some snails. All looking good but still this light covering of ash???

Starlings and wood pigeons leave a greasy film on ponds when they bathe. It disappears. 
Regular occurrence here 
The OP's photos aren't clear enough to determine if it's that though. Ponds have all sorts of things happening in them at various stages too, especially when new. Pumps are something I've never used, as they aren't necessary in wildlife ponds, so it may be something to do with that.

I think some of the solids will be a result of flocculation.
I'll let you Google it rather than try to explain.

Many thank you all for the suggestions. There are only a 5 goldfish and no birds bathing, so I can rule out animal waste.

I did manage to capture some slightly clearer photos. I wonder if it is a type of Algae or similar? Anything new that I put in the pond (like the net that you can see in one picture) gets covered in it within days.
