I'm wondering if anyone has seen an inline filter that I can use for vacuuming. I deal with some pools that don't have the best filters, and the owners can't afford to upgrade. With some of these filters, its not the best idea to put the stress of vacuuming on them. My concern is mostly with small old DE filters.
I'm looking for something small and portable that I can use either with an auxilliary pump, or as a prefilter. Is there something similar to a leaf trap out there that accepts a cartridge filter? Has anyone had to build their own? I'm looking for some ideas.
