Blue Coarse EF External Filter Foams

The fit is spot-on for my filter model, no trimming or fiddling needed—just swapped them in and the water clarity improved within a day. These coarse foams feel denser than the old ones I pulled out, so I’m hoping they’ll hold up longer this time around.

My canister filter is flowing like new again after swapping in these coarse blue pads—they fit perfectly without any trimming. The foam density feels just right for catching debris without slowing down the water too much.

Wasn't sure these would match my old filter sponges but the coarse cut slots straight into the media basket without any trimming. Nice to have the proper set instead of hacking up a generic block with scissors.
