Fish bring life and movement to your pond. They are not only beautiful and graceful but they also fulfil an important function in the ecological balance of the pond.
They feed on unwanted visitors to your pond such as mosquitoes and chrysalis and excrete nitrogen which is vital for pond plants.
If you want to keep fish in your pond you will have to provide the right conditions: The right size, shape and plants are just as important as the right technology to ensure the provision of oxygen as well as a constant current and movement in the water.
BIOsys filter systems and the pond aeration device Oxymax are just two great products amongst many effective choices from the OASE range.
The best time to add fish to the pond depends on the age of the pond or the pond water. In any case you should wait until the ecological balance in the water has established itself.
The OASE aqua activ water test set can help to check all the important water parameters. The right amount of fish for your pond can be roughly determined with the following general rule: Up to 1 kg (2.2lb) of fish per m³ (1000 litres) of

Plants for a koi pond need to be chosen carefully since koi love to eat pond plants. Therefore it is advisable to neglect sensitive little plants but choose robust plants like water cress instead.
