White particles in pond

[SeekerOfWine]

First, I have a bad string algae problem that I'm been working to resolve. Not sure if it is related but thought I'd mention it. This problem has been dogging me for about 3 years.

The issue that has me stumped is whenever I clean the algae by hand I'll see these white "particles" coming up from the liner surface. About the size of small pieces of sand. They are sort of grainy but I have no clue where they come from. Again, this has been around for a while.

Any ideas?

Do you think you could snatch a picture of them? or is it one of those things you cant... Could just be debris?

Will see what I can do. Not debris because it's been around too many years and there is too much of it.

Yes, a pic might help. There are a lot of knowledgeable, friendly folks on this forum. They will help you get to the bottom of this.

It may be exactly as you described.....sand!
