I have a small wildlife pond (4 metres x 2 approx.). It is about 10 years old and quite silted up, but I should get a few more years out of it before it turns into a bog garden and I have to start again. My problem is that it has become full of green algae. I can’t net it out, as it falls to bits. I thought of trying a chemical cleaner which is wildlife friendly (if there is such a thing) but as it is January, is it to early to try it? The newts should be coming back quite soon and the weed is tangled up with this stuff.
I too have a small garden pond that gives me such pleasure and grief!
Do you run a pump and filter in your pond?
After cleaning the largest of litter out of the water, relying on the filter to clean the finest material is a process.
The filter needs flushing every day during the first days of cleaning, then less often.
Slowly the finest material is removed from the water.
Patience and a good pond filter is recommended from my experience.
