I used Sonar earlier this year to kill off most of the weeds in my pond, it even reduced the FA.
However today I noticed several blooms of algae that didn't look like the typical green/light green FA.
Researching blue green algae is turning up lots of different images varying from a scum layer to mats of algae.
The current blooms are green with dark almost bubbling spots (like a bubble on a pizza).
Wondering if anyone has any idea, pics below.
Thanks
