12 Gallon Replacement Filter Sponge Alt V - MT-40-S

Looking for a replacement sponge for your 12 gallon Nano aquarium? You've come to the right place. This sponge from JBJ removes particulates and debris from your freshwater or saltwater tank. Clean water is important for the health of your fish and other animals.

The sponge in your filter should be replaced about once a month. However, you should not switch out all of your filter media at the same time, or else you could lose too much good bacteria.
