Hello,

I am in the PNW. I have a 130 x 45f pond that I use for RC boats. I am here to look for help in controlling the algae. Unfortunately, the pond has an outflow so my options are limited, I think.

About any algaecide should work when used in moderation. It’s not real expensive. To use caution, treat lightly on about 1/3 of the pond at a time.
