Tip: Never clean or change all the filter media together in one operation (and never clean too rigorously). When changing the Substrat Pro, mix approximately one third of the used filter media with the new material so that the purifying bacteria cultures multiply more rapidly.
Filter Pad Maintenance and Replacement
The white filter pad provides mechanical fine filtration. Since adhering dirt particles cannot be rinsed out completely, the filter pad must not be used more than once. Insert new pad. The same applies with the carbon pad. After excessive use, the collected pollutants may detach again; therefore, the pads may only be used for short periods (1-2 weeks).
The blue filter pad may be re-used two to three times. Wash gently under running water before re-inserting so that some of the resident bacteria are retained.
