Product Review

Package of SIX (6) replacement filter cartridges for the BT1 Betta Tank available on Amazon from Penn Plax.

These cartridges have been specifically designed to fit the filter used in the BT1 aquarium, so all you need to do is switch out the old one and replace it with one of these.
