| Joe : From experience, I don't think it makes a difference
Joe:
When I installed our first pond, I left the UV off for about a couple of months because I was too busy with other pond projects... A neighbor came over and mentioned that the water looked a little green... I installed the UV light and water cleared up...
When I installed our second pond, I installed the UV and turned it on when I filled the pond... Water stayed clear, and never had the slighest hit of green.
So from my experience, I don't think it makes a difference...
