After 6 to 12 months’ usage, the micro holes of sponge is gradually clogged by the tiny debris. So it is also recommended to replace the sponge once 6 to 12 months or when the sponge gets worn out. Review: I'm actually pretty impressed with these filters as they fit my Aquatop CF400UV canister perfectly. I'll definitely be buying them again, and I recommend them as well.
