Your thoughts and comments are welcomed

UV doesn't do anything to stop the hair algae (blanket weed). It can
only stop waterborn algae that turns your water green since it has to
go by the UV bulb. The blanket weed is common at the start of the
season since it seems to start growing before the rest of the plans get
going to compete for nutrients.

As JB says it could be that your filter needs cleaning.

The best remedy is to balance the pond so that the algae don't get the
nutrients. More plants will certainly help. I always get a large bloom
in Spring.
