String Algae take over?

Ive been dealing with string algae growing pretty continuously in my pond from August all the way until October. I am located in New England and its not growing now but there is a good layer, perhaps a foot thick that is lining the bottom of the pond. I removed alot of the algae in September and it grew back pretty quickly. I decided to leave it in for the winter as the fish love to hide in it, but I will be removing it all in the spring time again.

Is there anything I can do to prevent or limit the amount of string algae growth in the pond? I already have a UV light installed and that seems to help maintain water clarity; but string algae seems unaffected. Pond is roughly 10k gallons, max depth of 5 ft; with bass, bluegills and small bait fish.

Does your pond have a mud bottom? A couple of things you might try are aeration, tinting the water with pond safe tint, reducing the amount of nutrients entering the pond, say, from runoff, barley straw and using a bunch of floating plants and lily pads to shade the water.
Here is an interesting link that might help:
Barley Straw for Algae Control (psu.edu)

Are you sure it’s string algae? Do you test your water regularly?
Yes positive its string algae. I have not tested in a while. What should I be looking for when testing?


No it is not a mud bottom just firestone liner with some sand/ gravel in spots.

SHUT DOWN THE UV...... uv's kill live bacteria and live algae which in turn then becomes food for more algae. Some photos of your set up will help and describe filter and pump etc how many fish what type.
Aeration can possibly help
adding biotopes can help
tinting the pond can help
does the algae grow in fast flowing water or everywhere

If it’s not harmful, why fight it since the fish like it. It’s removing waste product from the water. Try adding more plants to out compete it for nutrients.
