I disagree. I get an algae bloom EVERY YEAR.

Let's see, this is like year 2 for you, isn't it?

I don't use a UV, have a great bio-filter on the koi pond (10 yo), have no
fish in the lily pond (5 yo). No suspended algae. I don't think your pond
has matured enough, I bet your will see, if you control the fish load, that
you'll have less and less algae bloom as the pond matures. ~ jan
