Does anyone know where I can get the DLS filter material used in the wet/dry pre filter? I can't find them in bulk. I want to make my own. I know TruVu and other filter companies sell them cut up to a certain size but I want to get large sheets for a custom filter. I can find companies the make and sell plastic mesh but nothing close to what that is used in the aquarium filters. Any leads to a supplier will be appreciated.
