Not sure if the picture loaded. But algae ID needed. When it is overcast, and cool, it is almost non existent. After a rain, none. Sunlight, it multiplies! I’ve seen it form. It looked like it was forming from the bottom of the pond.

If you can ID it, what are the causes? I recently died the pond Hopi g it would help. Has not helped.

I do aerate. (3) (2per stand@3 stands) 12” rubber cane diffusers. Around the clock aeration.


I can’t add a file. If I choose it from pic library it says it doesn’t have correct extension, if I take the pic it says it’s too big
