Re: "Powdery" algae?

Could it be dead algae from the UV?
Maybe it will eventually turn brown?

Have you heard of the 'garbage can filter'?

Route the water through the top of a garbage can full of
quilt batting, old clothes, bedding (something along those lines) with a hole
at the bottom. and see if you can 'strain' the stuff out.

"Sweater" algae - that's a new one on me. Google search turns up
nothing.
Problem is it clogs the foam filter on the Rio 3100 every couple days.
And if anything disturbs it, the water quickly clouds up. It does
settle back in reasonable time, though. Way too much of it for the
fish to eat.
Just ordered a Danner Pondmaster 2000 1' x 2' filter to use as the
pump input filter so it doesn't have to be cleaned so often.

It's much larger than pea soup algae.

It's alive and well.

Even though there's more than the recommended water flow in
this pond it's not enough to sweep much this stuff into the pump
so that it could be run thru such a filter. Plus, his current Tetra
filter is not all that much different from what you describe - it has
a couple batting-type pads that could filter this stuff out if you
could get it there. Plus, it clogs for pump foam filter before it
ever gets to the Tetra filter.

Sweater algae is substrate algae. Algae that is attached to something so this
is not what you have.

If you can not pull the stuff through the water fast enough to filter it all
out I'd empty the pond, wash it and start over. Also do as much as possible to
keep nutrients out of the water, such as sun, big water changes, fish poo,
fish food, decaying plants, fertilizers and dirt.

Steve,

You might try a vacuum system that sends the material outside the pond, like
a shop vac, or one of the hose end vacuums outfitted with an exhaust hose to
cause the discharge to go out of the pond rather than through the little
sock net. If it is heavy enough to not move to the filter readily, and yet
loose enough to create clouds, I don't know of any other way to get it.
