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.

Course sponge

It is a very nice sponge pad, and it won’t clog the pad that easy, thumps up 😂

My go to

I use this in all of my hang on back filters. I also resently used it in a pond filter.

Works Great!

I bought these because I wanted to move to all-sponge filtration. I use these in combination with the polishing pads to catch all the particles in my water. These pads really do a great job holding all the detritus until I can get them cleaned! That’s what I really needed. They work great!! Thanks!!

Filter essential

This is the best truly coarse filter material I’ve found. Wonderful to use as the bottom layer in a hob and on the filter intake. Keeps small fish safe and keeps plant leaves and large detritus from clogging up the filter

No more clogging

Cutting the material is so simple I could do it with regular household scissors. The width is perfect for the nano hob I purchased from Aquarium Co-Op too.
