Our well water has high levels of calcium and some

stabilized, still water overnight reveals next morning
ultra-fine yellowish powder on the bottom. It is so fine it
goes straight through the sand filter and back into
the pool, making the water cloudy and greenish.
Is there any cure for this, perhaps by causing the
dust to agglomerate so that the sand filter holds it?

I don't know nuthink about pools, really, but I'd think best bet would
be to install 10 micron filters on supply line to minimize the amount
introduced.

As for collection of what's there, no real idea other than also
filtering the recycle altho don't know what that capacity might entail.

I'd presume a pool service company of any competence could respond
appropriately.
