MAINTENANCE AND CLEANING

• If necessary, clean with clear water using a soft brush.
• Do not use cleaning agents or chemical solutions.
• Cleaning and replacement cycles for filter media are dependent on the size of the aquarium and the number
of fish. Therefore, it is necessary to clean and replace the filter media as required to ensure optimum filter
performance.
• If there are several filter foams: Clean or replace the filter foams at different times. This saves enough useful
bacteria to ensure good biological filtration of the water.
NOTE
Thoroughly rinse out all filter material with warm tap water before using for the first
time in order to remove any soiling. (→ Cleaning/replacing the filter media P.17)
