Marineland 24-Pack Penguin Rite Cartridge, Size C

Just what I needed....

Need plenty of threse around. Have a large aquarium.

Great Deal! Definitely a must with my fish tanks! Works as directed and very sturdy and strong. Buy with confidence!

Nice convenient way to keep your fishtank clean and healthy. Also not expensive through Amazon. The pet stores mark these way up.

I was very happy with the purchase. I use a lot of these filters, and this bulk package was a good price.

The wife loves the bundle package, and this is her favorite filter. This is a great deal for the cost!!

everything was in the package and the filters work great and was not damaged in shipping. I keep these in my cart all year around so when i eventually run out i can buy bulk more. DO NOT GO TO THE PET STORE!!! I PRICED THEM OUT AND YOU GET A CASE FOR FREE BUYING FROM AMAZON.

Product as described!

My filters came right on time... An added bonus was you got two free filters in each box, love it!

This is about the third time I have bought this product. Usually, I just get them on line for convenience, but this time I was ill and could not get out of the house. I was able to get every thing handled in about two minutes and then get back to bed. A top quality product delivered to my door at an excellent price. Im happy and my tank is crystal clear.
