Once you have established good biofiltration again, and we, the group,
have determined that your biofilter is big enough for your pond, you
might consider a UV filter. Appropriately sized, this will stop green
water dead in its tracks.

A temporary solution, that you could do right now, would be to toss in
a bunch of calcium bentonite clay, while your system is circulating.
You should be able to find this at any koi supply place. Don't be afraid
to use treble or quadruple what they recommmend. Expect muddy water for
a day or so, nothing wrong, to be expected. Then everything should clear
up, see all the way to the bottom type of stuff.

What does the bentonite clay do???
