Green Scum on Pond

This was recently sent in from a pond owner: "I have a small 1 acre or less 15 year old pond 10' at deepest. Last year and this I had very bad covering of floating scum. I would like treatment advice and total pond care after treatment."

We requested he send us some photos to identify his growth.

This floating pond scum is called planktonic algae. The treatment we recommend is liquid copper sulfate like our Crystal Plex.
