Garden Pond

My garden pond didn’t lack the latest technology when it was first installed but that was forty years ago.  Now it needs  pond uv filters since water was turning green and the constant cleaning was getting tedious.  My gardener suggested pond uv filters that eradicate bacteria and hovering algae that seemed everywhere.  Even if pond uv filters are not entirely a solution to planktonic algae, at least the space between cleaning time has dramatically changed.
