we are already on our second day of crystal clear water.

I would never have recommended a gravel anything for in the pond or out of
the pond filter, because of the difficulty of cleaning them. The problem
all boils down to dirt & dust that don't break down, as organics do
break-down.... unfortunately as the organics build-up and break down they
use up a pond's buffer and can cause pH crashes... so be diligent about
checking your KH in the coming years and adding baking soda as needed.

As is, I'd say, leave it alone, the green algae on top will break down on
it's own, and once plants fill in, you won't see it. ~ jan
