Gday
I've been out of the pond game for a few years and Ive come back to
discover that many of the external filters now have inbuilt UV
steralizers.. is it generally accepted that these are the way to go now or
is a biological/mechanical only filter ok? I understand the UV can help
reduce greenwater, but are they worth the extra cost?

Thanks
