Review: Cut to size and rinse often! - This foam is easily cut to size for whatever function you plan. I use it in my FX4 aquarium filters and it's the best!
Review: Murky to clear - I use this around a pump in my pond (300gal) to filter out the gunk. Works well. Every so often I power wash it to clean out the build up and put it back. Makes the water turn from murky to clear.
