This is njbiology, robyn.
I read on your site that your pond is crystal clear and you have no barley or UV light, etc.
My pond is in full sun light. I cant see past 10 inches - very yellow green. What can i do - 60 square feet - only a few lilly pads and a lot of irises and pickerel. can i get mine chrystal clear - i have a500 gph pump but only 270 gallons. what can i do? dont want to get a uv sterilizer either.
