To promote the natural balance of the water and the vitality of the fish, it is advisable to apply EM-1 once a year in the aquarium. Sometimes it is necessary to provide the aquarium with extra oxygen afterwards. The use of EM ceramics in the filter system or loose on the bottom improves the water quality.
TIP : When cleaning the filter system, rinse the ceramic stones with fresh water.
Advice: 1 litre EM-1 in 1000 litres of water In the filter system: 1 kg ceramic / 1000 litres of water
