- 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
These coarse sponge pads are a much better alternative than replaceable cartridges for HOB filters. Just lightly rinse the dirt from the sponge once a month. I have some used for over 3 years. Time to replace them.
On account of upgrading a hang back filter, this course sponge is the ideal fit. The water does indeed flow through better than the stock filter that was used with the earlier hang back filter. Thanks to a Corey video demonstrating this course sponge, changes were made.
I used this to replace the cartridge on my new 5 gallon quarantine tank. I also cut a piece to use to keep my shrimp from getting sucked into my water change gravel vac. I still have some left, but I decided I wanted a spare. I will use this to replace my aquaclear sponge whenever it wears out too. I like that it seems coarse enough to make it hard to clog.
The sponge pads are excellent they filter well and would recommend to anyone who has a aquarium 🥰
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.
