Hello-

I have a rather small pond, it is 6x2x2 and uses a fountain pump rated at
450 GPH. I have one plant in the pond and the pond water is murky green. I
regularly clean the filter, and have done 50% water changes. I put in some
chemical that is supposed to kill algae and is not harmful to fish or
plants. But...the algae is uncontrollable. Any suggestions from this group
would be appreciated.

Thanx
