Oddball;602938; said:My wider wet/dry filters use floor stripper pads. They're made of the same polyethylene plastic but are a little stiffer. They work great for large filters pushing alot of water since they don't compress under pressure as much as scrubbies or other materials do. They're available in a wide range of diameters and thickness. And, I've found them on occassion for US.99 cents for a 5-pack (ebay). Here's a pic of the pads, from a New Zealand company. So, you shouldn't have a problem finding them locally.
BTW, who's ripping you off on the FX5? I bought 3 of them, off ebay, for $185 + $38 shipping/each.
I have gone to some of the local businesses and asked if I can take the centers of their pads. They look at you funny, but generally say ok
