…is clear.
It wasn’t yesterday. It was green murk.
Today, though I did absolutely NOTHING…
It’s clear. You can see the rocks on the bottom.

It’s my theory that the bursting of the sand filter gasket that dumped sand and dust into the pond, turning it milky for days…has finally done what sand does when you dump it into bioactive water, and gathered a shell of bacteria about each dust particle. There is, indeed, a fine dusting of sand all over the bottom.

The not-too-cheap actual filter I ordered is still on its way.

It will undoubtedly be useful.

But now the water is so clear our fish look suspended in glass.

Go figure.
