The small sponge fits perfectly with my hang-on filter. It stopped my shrimp from getting sucked in and caught leaves before they reached the main filter. Easy to clean and stays in place well.

I used the medium size for my canister filter. It works as a good prefilter and keeps debris out. It stretches nicely and doesn’t fall apart after a few cleanings.

Great product for preventing fish from being sucked into the filter. The small size fits my inlet perfectly and the material is durable. I’ve cleaned it weekly and it still holds shape.
