Natural waste covering the oxygenating plants in water

[Rach]

It's natural waste but does annoy me! I feel I have to 'dust' the oxygenating weed and any rocks that are under water as they get covered in this dust like waste.

anyone found anything that dissolves this?

It's great to be free for 18 months from blanket weed (naturally) but I now have this new 'annoyance'!

I would increase the water circulation to prevent detritus from settling on the plant leaves.

Adding chemicals isn't really a good way to get rid of anything annoying in a pond despite what the bottle may say. It's very tempting to slosh a load of goodness knows what into the water, but very often, you can end up creating more problems than you started with! It just creates extra dead material that needs to be got rid of by some other means, which has the effect of altering the water's chemical balance. This is especially so if you have fish, which by the sound of your problem, you do have.
Presuming you have a water circulating system of some kind, through a filter and maybe a waterfall/fountain/outfall of some kind, the intake to the pump should be as far away from the return back into the pond to create a current which will help somewhat with water movement below the surface. Maybe move the pump around the pond to a different place where it could suck up some more detritus? It may have cleared one area and just needs a relocation every now and then? I never leave my pump in the same place, it gets moved around randomly.

@Rach Agree that adding more water circulation will/should help! That will not only keep the stuff moving and off the plants, but will keep it moving toward your pump/filter where it can be removed.

What kind of mechanical filtration do you have? And how often are you cleaning it?

Thanks for this, logical but I had not thought about this. The pump and filter system is from Hozelock Bioforce.
I shall have to extend the tubing though as we didn't think about this when installed. So I will need to dig it up. Maybe do once the lilies have died down as I can't move those at the moment. They are in baskets but when I triec to get one out it seemed impossible!
