Something *ate* my filter media?!?
You may not be able to go with the micron filtration media. I use that in my canister filter systems but they have a lot more power and are closed systems so they “force” the water through the micron polishing pads. I’m not sure an HOB filter or an in-tank filter would work with that type of filter media. The blue/white poly-pad is a dual layer with one having a denser mesh than the other so it does a good job of catching most stuff.
