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.

Excellent Coarse sponge

No longer have to buy the replacement cartridges for my hang on back filters. I just cut the foam to size and along with the water polishing white pad does the job ! Thanks Cory
