    Adding DE to Cartridge filter

    I read somewhere online awhile ago that you can add DE to a cartridge filter. Is this possible/recommended or will it do damage to the cartridge?

    Some cartridge filters are compatible with DE. You would need to check to see if the specific filter model is compatible. Adding DE to a standard cartridge filter will clog it up.

    Re: Adding DE to Cartridge filter

    Use very little de. this is mainly to help with later cleaning of the cartridge. Not really to help with filtering. I practice this. and have not had any real difference in the clarity of water either way, i do it for the ease of cleaning.
