So how many types of algae are there?

Steve, I forgot to say that though some fish farmers advocate adding barley straw the moment the temps even begin to warm up, others say to keep the treatments up all winter long. Their reasoning is that even in February we can have unseasonably warm days & it doesn't take much of a temperature spike for algae to become active again.

Hi Gerald. I think you're on to something here. Last year, I could watch the algae float up from the bottom of my shallow stream. It would float up in the daytime and sink at night. Last year it was big globs.
So far the UV is having no affect.

I have had some success in the past with Barley Straw Extract and Partial Shading but it does need to be applied regularly

Algae will "Float" to the surface during Sunlight hours as you have noticed..

Give the UV time - if it is correctly sized for the Gallonage/Flow/Stocking Densities/Pond Positioning etc it should keep it under control but O3 would work better

Does anyone know the name of this particular algae? It doesn't sound like regular pea soup algae or string algae. It's got some peculiar traits.

I can't post what I call it.
