Activated Carbon Filter Cotton 35*15*5

This porous, carbon-impregnated sponge block is designed precisely to these dimensions (35cm length x 15cm width x 5cm thickness). It provides dual mechanical and chemical filtration by trapping waste while adsorbing odors, toxins, and water discoloration. 

Usage Tips

Rinse before use: Rinse the sponge thoroughly in clean water before placing it in the tank to remove any loose carbon dust.

Filter placement: Place this sponge after your coarse mechanical foam to ensure it doesn't clog prematurely with heavy debris.

Replacement schedule: The chemical absorption properties of activated carbon typically last 3 to 4 weeks, after which it should be replaced.
