Coarse sponge pad is a replacement for throw away 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 pad

I use the coarse sponge pad as a layer of media in my HOB filters. It’s great because you can cut them to size and they last forever.

Quality coarse sponge pad

This sponge pad was cut up to fill the first chamber of a UNS 45 all in one so no fish or shrimp got out of the main tank. It worked perfectly!

12 x 12 Coarse Sponge

These have become hard to find and when you do then tend to be "too fine" or densely celled for my use. Aquarium Co-Ops may not be better BUT it is always available and cheaper than most other sources. Gets full 5 stars!

Sponge filter

Aquarium Co OP always has the best course sponge material.

I watched Cory's video on hacking HOB filters. So.....I immediately ordered the coarse sponge pad. Next, he suggested a pre-filter for the intake. Unfortunately, even the smallest size wouldn't fit so alas....BUMMER. When my box from Aquarium Co-Op arrived I cut the sponge to size added it to my Aquaclear and removed the carbon. Then, I thought what if I cut a piece of sponge and then slice a small pocket and then slip it on the end of the intake tube....and you know what....it worked. I placed one on the HOB intake and on the powerhead intake. It's like having a sponge filter that my fish enjoy snacking from and it keeps the big stuff out of the filter. Been running it this way for about a month and I think it has been a success!
