Just treated this pond for algae, any idea what this coloring could be?

These type of things are difficult to diagnosis with photos. Maybe this field guide will help you narrow it down...

Welcome to the forums!

Thanks for your reply and helpful document! It’s hard to diagnose based off this too.

Is it common if I treated a week or so ago that this is a new algae or is it the other stuff dying?

Thank you!
