Your phosphate level is too high. Are you using pond PH adjusting/buffering
chemicals? They are mostly phosphate. Do you add miricle grow sticks or
other "land plant" fertilizer in your water or to the dirt for plants that
are located in water? They are usually high in phosphate. You can purchase a
phosphate kit at the pet store for about $15.00-$20.00.

This is my second summer with my pond. Last year, my water was crystal
clear,
and I attributed that to my wonderful care (LOL) and the UV light. This
year,
I have so much string algae, that I hate looking in the pond every
morning.
The water quality is fine, I just checked everything yesterday. Any
suggestions?
