GREAT product! This was the EXACT replacement filter We we’re looking for. We could NOT find them in any pet store so we checked online and went with these guys. Our order came just as we expected in a timely manner and we are very satisfied and will definitely reorder when we are all out.
Great Value. Order arrived within a few days. They work great. Very, very pleased. Will purchase again in the future.

Perfect. Does what they are supposed to do. Water clear as crystal. I also use a whisper filter on the back of aquarium and turn off to feed fish. If I forget to turn outside filter back on then the Penn-Plax undergravel filter keeps water sooooo clear. These cartridges really do the job well. I change these cartridges once every month.
