I'm South facing and have a large surface area:volume ratio and after struggling with algae erected a pergola over part of the pond and placed black gardeners shade/wind netting over the top. This made a big difference enabled me to drop the size of UV from 110W to 55W.
I've tried various blanket weed treatments and reverted back to Cloverleaf Blanket Answer as the best/most consistent.

It might be a recurring problem for you, don't wait for it to become a big problem at the first signs knock it back with a suitable treatment. Sometimes if you have let it get hold you may have to retreat(follow manufacture's directions).
Some people find that changing the treatment every couple of years is more effective (don't know the science but the blanket weed seems to adapt to be immune to the treatment, some people find).
The treatment that I use has worked for several years and I don't see the need to change yet .
Be very careful to follow manufactures instructions many people have had problems with blanket weed treatments.

The best stuff around in my opinion is Aquasource Resolve, no clouding of the water and works a treat. No mixing or measuring out I just sprinkle a good dose of it around the pond walls and as it falls through the water it will stick to the walls of the pond a bit too. Great stuff
