Coarse sponge pad is a replacement for throwaway cartridges in aquarium filters. Not only are the cartridges costly, they are also bad for the environment. Coarse sponge pads can be reused for many years with normal use. With this porosity of the foam, they are nearly clog-proof. They also filter out larger particles of waste before getting to your fine filter pads or bio rings.
Coarse Sponge for Mechanical Filtration
Mechanical filtration refers to sponge, foam, and polishing pads that physically strain out debris from the water, much like a coffee filter. We chose a coarse sponge with large pores because it's good for blocking most debris like fish poop and dead leaves without clogging up so quickly that you have to constantly clean it.
Customizable to Fit Any Filter
Whether you have a hang-on-back, canister, or sump filter, this coarse sponge pad can fit them all. Just grab a pair of scissors and cut the sponge into the right shape. To clean it, simply remove the sponge from the filter and squeeze it multiple times in old aquarium water until all the brown gunk is removed.
The Aquarium Co - Op Course Sponge Pad is great! You get a lot in one package. It’s the best course pad available.

Worked perfect
I used this to modify my hang on back filter to be more betta friendly - it did the trick. It’s big and I easily cut it to size and I have plenty of extra for future use too. Would order again!

Great for reducing flow of aquarium filter!
Was easy enough to cut into squares and perfectly course enough so that i could have something to put into my filter’s out stream and ease the flow that was flinging around my poor tetras:’)

Sponge Pad Coarse
I used the sponge pad to baffle my hang-on-the-back filter because my beta fish needed it. The sponge worked like a charm.
