Most quality filters are coated with colloidal silver to provide some protection against bacteria. It's not like this. If you don't add antibacterial agents every time you refill the tank, these untreated filters will go moldy within a week. Spend $10 more and get cleaned filters. The service life is significantly increased and in the end you save money.
