JBJ 28 Gallon Nano-Cube Replacement Sponge (2-Pack)

I was missing filters for my newly purchased filters and these did the trick.

Fits and looks the same as the original

Good quality; smaller than expected but fits tank. Will be shopping again soon for refills. Thanks!

Perfect fit for nano-cube, very good for filtering large particles.

not the right size for the 24 gallon Nano

Precisely what I was needing!! And then Some. C I'M TRYING TO KEEP MY FIDDLER CRAB FROM DROPPING DOWN BY THE IMPELLER IN MY TANK, THESE WORK GLOROUSLY PLUS THEY HELP KEEP OTHER CRAP FROM GETTING CHEWED UP OR BLOCKING THE ONLY PUMP MY TANK HAS!
