Interpet PF4 Super Fine Filter Pads - 5 Pack
To remove very fine particles that may have passed through the plain and carbon foams, you should use these super fine filter pads.
These will remove minute particles and will give your aquarium a sparklingly clean appearance. Simply add a pad next to the carbon foam.
The filter pads are disposable and should be replaced every 2-4 weeks to ensure your filter operates at maximum efficiency.
If you find that the pads are blocking too frequently then remove them. This may indicate over feeding or over stocking of fish. Increase the frequency of your partial water changes and lower feeding before using the pads again.Interpet PF4 Super Fine Filter Pads Part No. 2253
