Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Close up of Plankton bloom?

Timinator, I believe Sonar to be an herbicide (Fluridone?) which my understanding is ineffective on algae including FA.

I've used it before for Coontail and Duckweed and you're correct, it's very expensive but very effective on vegetation!

I believe the BG algae and the like (cyanobacteria) to be common during summer months especially on calm waters (brought on by hot, sunny days?) which is why I was wondering if adding O2 (running the outboard) would be effective.

Thanks!
