Q2. How often should I change my aquarium filter cartridge?
Ans: For optimal aquarium health and steady water flow, it is recommended to replace the cartridge every 3 to 4 weeks. Heavy bioloads may require more frequent changes.
Q3. Can I leave the cartridge inside the filter while treating fish with medicine?
Ans: No, you should temporarily remove the cartridge during medication cycles. The active carbon inside the cartridge will absorb and neutralize the treatment from the water.
