The pond had been struggling to find its groove this year. Algae has been consistent and water isn't as clear as usual. The pond is in shade for the majority of the day, it gets around 5-6 hours of sunlight across half the pond. I am based in the south of England. There are a good amount of oxygenators in the pond and lots of plants.

Any ideas or anything obvious from the pictures that I am doing wrong and any suggestions on how to help. Or even if this is a problem at all.

Thanks in advance.
