Also, have never changed the water in the pond. But of course, living here on the coast with the rain, as a lot to do with that. I have finally had to start adding water now to keep it full,.... last time for that was back last fall.

Ya I find that a UV definitely helps with that suspended algae that greens your water. I try to replace my UV bulb every season. I don't know if that's overkill or not but it definitely helps. The bulbs can be a challenge to source at the beginning of the season.
