Pond treatment and fish keeping

When the pond is completely full, it will be several weeks before an ecological balance is established and the fish can safely be added to the pond.

This maturing process can be acceleratedwith water treatment products that turn tap waterinto pond water with values close to nature. We recommend EHEIM basic water treatment products.


For determining the quantity of fish, the correct treatment dosage and the right technical products, it is necessary to know the amount of water your pond holds. If it was not possible to measure the volume with your water meter during filling, it can be calculated using our pond calculator.
