Filter for the garden pond and purification system
Pond purification systems and filters are available for different pond sizes. For smaller ponds from 100-5000L (if there are fish, you should oversize a bit, look at the filters for more info) you can use the combiclear filters where you have everything in one box, pump, filter and UV.
If you have a larger lake, you should have a bioclear filter on land and a pond pump in the lake.
