Laghetto naturale o laghetto artificiale?
Both ponds have a lot in common, but there are some differences too: Artificial ponds rarely have a natural inlet and outlet. This means they only receive fresh water in the form of rainwater and direct action such as a partial water change. Please remember that Rainwater is important, since rainwater lowers the mineral content of the water in an artificial pond and some maintenance is needed.
The natural pond doesn’t have a liner or shell as a bottom, but has earth, clay or other soils instead. All ponds, regardless of whether artificial or natural, tend to silt up when leaves fall or when any organic matter, such as branches and twigs, enter. In the long run this is a real problem for artificial ponds and you need to take action before the “sludge” in your pond can either i) lead the bacteria in your pond to consume too much oxygen breaking down the sludge, or ii) reduce the depth of the pond, which can jeopardise the fish’s survival in winter. Mechanical sludge removal and the use of special bacteria with active oxygen ( JBL SediEx Pond ) is essential.
Don’t be surprised to find animals you have never seen before in your pond! Bird faeces can contain the eggs of a variety of animal species. Frogs and newts moving across the landscape may choose your pond as their new habitat.
Koi ponds can differ from other artificial ponds. They often have vertical walls, no plants, no substrate and a bottom drain with a strong filter system. This type of pond is least like a natural pond.
