- Coarse foam
- Reusable
- Fits all filters
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.

Customer Reviews
I cut it to size to fit into my hang on filters, it does a good job catching unwanted debris floating around my tank. I clean mine about every two weeks running them under water, very easy cleaning.
These are my favorite coarse filter pads in that they don't clog easily and rinse well. I wish they came in larger sizes.
I like the coarseness of the filter pad. I've been replacing the standard sponges with this as they ware out. They last forever and don't clog with debris. easy to cut and clean. Two of the bigger pad nicely fit and fill an Aqua Clear 110. It's almost like Cory planned it that way~!
I watch ACO for most of my knowledge about fish keeping (PS 1st tank). Cory gave me the confidence to ‘hot rod’ my canister filter.
I was having cloudy water. This is what the new sponges accomplish! No water change; just new filters!
I’m blown away!!!
Will work for a modification for my sump. And hob filter
I use this in conjunction with the polishing pad and bio filter media.
The Black Sponge is great in my Aqua Clear filters, doesn’t clog up, grows lots of Bacteria. I like to run a fine filter pad ,along with the black sponge periodically for water polishing. Last for just about forever .
It works good for the filters.
I cut pieces off and usually use this sponge as my first sponge in series of sponges. It doesn't clog fast at all and I think its houses beneficial bacteria well. I've also used it as a prefilter sponge but you have to cut it exactly down the center to get it to fit right.
The Aquarium Co - Op Course Sponge Pad is great! You get a lot in one package. It’s the best course pad available.
