How do I get rid of green covering on pond
I have tried everything I can think of - have got pump running 24 hrs a day
with a UV filter supposely killing algy - throw pond salt in every day
(should I be doing that) - we haven't got any blanket weed or snails - about
8 very large koi and 8 small ones live in the pond - would love it to look
crystal clear.
