Good to hear you taking such great care of your fish. They will love
you for it.

I'd say about 1/4 of the pond is covered by bright green algae now.

Sounds like blanket weed. You can pull it off...although it is
grabbing nutrients for you.



I turned on the winter bubbler to at least add additional aeration, and
bypassed the main filter so the uv filter can at least slow things down.

The UV should kill the green water fairly fast.

Your fish will love even more for adding the bubbler. Any chance of
having the pump just circulate the water...as in make it circulate to
the surface where it can exchange gases? We have a bypass that allows
the pump to skip the berm ponds but continue to circulate water. It
actually runs in from a 1.5" pipe set just above water level. Talk
about a jet!
