This unique filter is specifically designed with limited space in mind. Slender housing makes this filter more aesthetically pleasing than other bulky box filters and with Hagen, you know you are not sacrificing quality.
Bio-Guard filtration is designed to optimize and maintain biological filtration. Each Slim Filter is equipped with 2, 3, or 4 filter cartridges. By alternating cartridge replacement, the Bio-Guard system ensures rapid cartridge seeding of beneficial bacteria, ensuring proper biological filtration for a clean and healthy aquarium.
For best results, replace 1-2 filter cartridges every two to four weeks.
1. Turn power filter off and remove filter cartridge.
2. Rinse filter cartridges thoroughly with tank water and put back or replace.
IMPORTANT: Do not use tap water as this will kill the beneficial bacteria in your foam. NEVER use soap or detergents as these products could be harmful to the inhabitants of your aquarium.
3. Replace filter cartridges when water starts to overflow as illustrated in the instructions.
