I have just bought a house with a couple of large ponds (2500 litres and 1500 litres at a rough guess) in the garden. I know nothing about fish or ponds so am seeking some advice about how to look after them as well as some good/reliable on-line resources.
There is a strong possibility that there are some Koi in the larger pond, as well as some other similar fish. There's also some black fish too!
The smaller pond has a pump/filter and a water feature that fills a small top pond (with no fish) that then water falls into the main part of the pond. The large has no pump/filter as the previous owner took it, along with his Koi (or most of). He originally had a large pump, with a UV light in it.
How do I not kill them?!
Any help, gratefully accepted.
P.S. I have also inherited a couple of white doves... How do I look after them???
