- Coarse Foam
- Reusable
- Fits all Filters
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.
Customer Reviews
When I first heard about using the course sponge pad and other media, besides pre-made materials in the petshop it scared me. I watched a video on the AquariumCoop website and gave it a try years ago and I was convinced. It worked so well. My fish are healthy and happy and I save lots of coins!
I purchased to add to my filter. Easy to cut to size needed. Works as it should.
I replace my cartridges with this on the hang in the back and it works great
I have ordered a few of these sponges over the last couple years. If I am short a bit to get free shipping, this is my go-to item. I used them in filters, obviously, but I also use them in my science classroom for a variety of projects including eco-columns. I love that they aren't too dense. My next plan for them is to use them to divide the sump on my 75 gallon into compartments without hindering water flow.
This stuff is great! I use this before and after a finer sponge in my HOBs. Before it acts as a prefilter and after it's biomedia. I like it better than traditional ceramic rings as it is much less likely to clog, much easier to keep clean, and still provides excellent surface area. This is one of those products I wouldn't want to go without.
